［実施形態］
図１は、本発明の一実施形態に係るコンピュータ装置１０のハードウェア構成を示したブロック図である。コンピュータ装置１０は、本発明に係る評価支援装置の一例であり、桟橋に外力が作用したときに生じる損傷に係る情報を出力する機能を有する。本実施形態においては、コンピュータ装置１０は、パーソナルコンピュータである。
[Embodiment]
FIG. 1 is a block diagram showing a hardware configuration of a computer device 10 according to an embodiment of the present invention. The computer device 10 is an example of the evaluation support device according to the present invention, and has a function of outputting information on damage caused when an external force acts on the pier. In the present embodiment, the computer device 10 is a personal computer.
操作部１０４は、キーボードおよびマウスを有する。オペレータは、操作部１０４のキーボードやマウスを操作することにより、桟橋の評価に係る各種データを入力する。なお、各種データの入力は、キーボードやマウスを用いる構成に限定されるものではなく、例えば、音声入力や画像認識による入力で行われてもよい。ディスプレイ１０３は、コンピュータ装置１０を操作するためのＧＵＩや、桟橋の評価結果を表示する。 The operation unit 104 has a keyboard and a mouse. The operator inputs various data related to the evaluation of the pier by operating the keyboard and mouse of the operation unit 104. The input of various data is not limited to the configuration using a keyboard or mouse, and may be input by voice input or image recognition, for example. The display 103 displays a GUI for operating the computer device 10 and an evaluation result of the pier.
記憶部１０２は、ハードディスク装置を有し、取得したデータに基づいて桟橋の損傷に係る情報を出力するプログラムを記憶する。また、記憶部１０２は、複数の桟橋について、梁の劣化のパターンを複数設定し、設定したパターンのそれぞれについて外力が作用したときの構造解析の結果を格納したデータベースＤＢ１を記憶する。 The storage unit 102 has a hard disk device and stores a program that outputs information related to damage to the pier based on the acquired data. Further, the storage unit 102 sets a plurality of beam deterioration patterns for the plurality of piers, and stores the database DB1 that stores the results of the structural analysis when an external force acts on each of the set patterns.
図２は、記憶部１０２が記憶するデータベースＤＢ１の一例を示した図である。解析ケースの列には、梁の損傷のパターンを識別する番号が格納される。構造解析結果の列には、桟橋に対して外力が作用したときの損傷の構造解析結果が格納され、例えば、外力として桟橋に接岸する船舶から桟橋が受ける接岸力、レベル１地震動、レベル２地震動が作用したときの損傷の構造解析結果などが格納される。なお、図２に示した外力は一例である。外力は、前述のものに限定されるものではなく、クレーン作業荷重や牽引力などを含めてもよい。構造解析結果の列に格納されるデータは、本発明に係る構造解析結果の一例である。 FIG. 2 is a diagram showing an example of the database DB 1 stored in the storage unit 102. The analysis case column stores a number that identifies the pattern of beam damage. The column of structural analysis results stores the structural analysis results of damage when an external force acts on the pier. For example, the berthing force received by the pier from a ship berthing at the pier as an external force, level 1 seismic motion, and level 2 seismic motion. The structural analysis result of the damage when the action is performed is stored. The external force shown in FIG. 2 is an example. The external force is not limited to the above, and may include a crane working load, a traction force, and the like. The data stored in the structural analysis result column is an example of the structural analysis result according to the present invention.
なお、図２に示した例では、構造解析結果として、梁の総面積に対する有害ひび割れ領域の割合（面積率）、梁の総面積に対する降伏領域の割合（面積率）、梁の総面積に対する終局領域の割合（面積率）を示している。有害ひび割れ領域については、港湾の施設の技術上の基準に基づき、予め定められたひび割れ幅の限界値を超える場合を有害ひび割れとし、有害ひび割れ幅が存在する梁の領域を有害ひび割れ領域としている。降伏領域については、弾性範囲を超え、塑性領域に達している梁の領域とし、終局領域については、破断等の終局状態に至る梁の領域としている。なお、構造解析結果は、前述のものに限定されるものではなく、例えば許容応力に達している梁の領域等を含む構成であってもよく、任意の判定基準を満たす領域の割合（面積率）を格納できる。また、構造解析結果として格納される面積率については、前述の面積率に限定されるものではない。例えば、桟橋上部工の総面積に対して、損傷した梁の面積および損傷した梁に隣接する床版において損傷した面積が占める割合を面積率としてもよい。床版において損傷した面積は、例えば、床版を受け持つ梁において損傷した梁の本数に応じて求めてもよく、例えば、床版を受け持つ梁の数が４本であり、そのうちの１本の梁が損傷した場合には、床版面積の１／４が損傷しているとして面積を求めてもよい。 In the example shown in FIG. 2, as a result of structural analysis, the ratio of the harmful cracked area to the total area of the beam (area ratio), the ratio of the yield area to the total area of the beam (area ratio), and the final result to the total area of the beam. The ratio of the area (area ratio) is shown. Regarding the harmful crack area, based on the technical standards of the port facilities, the case where the limit value of the predetermined crack width is exceeded is regarded as the harmful crack, and the area of the beam where the harmful crack width exists is regarded as the harmful crack area. The yield region is the region of the beam that exceeds the elastic range and reaches the plastic region, and the ultimate region is the region of the beam that reaches the ultimate state such as fracture. The structural analysis result is not limited to the above-mentioned one, and may include, for example, a region of a beam that has reached the allowable stress, and the ratio of the region (area ratio) that satisfies an arbitrary judgment criterion. ) Can be stored. Further, the area ratio stored as the structural analysis result is not limited to the above-mentioned area ratio. For example, the area ratio may be the ratio of the damaged beam area and the damaged area in the floor slab adjacent to the damaged beam to the total area of the pier superstructure. The damaged area in the floor slab may be obtained, for example, according to the number of damaged beams in the beam in charge of the floor slab. For example, the number of beams in charge of the floor slab is four, and one of the beams is one of them. If is damaged, the area may be calculated assuming that 1/4 of the floor slab area is damaged.
損傷度の列には、損傷の構造解析結果から算出した桟橋の損傷度が格納される。損傷度とは、外力に応じた桟橋上部工の構造解析結果を一つの指標で表したものである。桟橋上部工とは、例えば桟橋の梁である。損傷度は、構造解析で得られた有害ひび割れ領域、降伏領域、終局領域の算出結果を予め定められた式に導入することにより算出される。上部工劣化度の列には、梁の損傷のパターンから算出した梁の上部工劣化度が格納される。梁の上部工劣化度の算出方法については後述する。 The damage degree column stores the damage degree of the pier calculated from the damage structure analysis result. The degree of damage is the result of structural analysis of the pier superstructure according to the external force expressed by one index. The pier superstructure is, for example, a beam of a pier. The degree of damage is calculated by introducing the calculation results of the harmful crack region, the yield region, and the ultimate region obtained by the structural analysis into a predetermined formula. The column of superstructure deterioration degree stores the beam superstructure deterioration degree calculated from the damage pattern of the beam. The method of calculating the degree of deterioration of the superstructure of the beam will be described later.

The output unit 1004 is an example of the output means according to the present invention.
次に本実施形態に係る桟橋の損傷の評価方法について、図４のフローチャートを用いて説明する。オペレータは、損傷を評価する評価対象である実物の桟橋Ｐについて設計図を参照し、桟橋Ｐの梁を仮想的に表すモデルを作成する操作を操作部１０４で行う。桟橋Ｐは、本発明に係る評価対象桟橋である。コンピュータ装置１０は、オペレータが行った操作に応じて桟橋Ｐのモデルを生成する（ステップＳ１０１）。次にオペレータは、生成したモデルに対し、桟橋Ｐの上部工である複数の梁の各々の劣化度を示す劣化度データを操作部１０４から入力し、コンピュータ装置１０のデータ取得部１００１は、入力される劣化度データを取得する（ステップＳ１０２）。劣化度データは、本発明に係る梁の劣化度判定結果の一例である。 Next, a method for evaluating damage to the pier according to the present embodiment will be described with reference to the flowchart of FIG. The operator refers to the design drawing of the actual pier P to be evaluated for damage, and the operation unit 104 performs an operation of creating a model that virtually represents the beam of the pier P. The pier P is an evaluation target pier according to the present invention. The computer device 10 generates a model of the pier P according to the operation performed by the operator (step S101). Next, the operator inputs deterioration degree data indicating the deterioration degree of each of the plurality of beams which are superstructures of the pier P to the generated model from the operation unit 104, and the data acquisition unit 1001 of the computer device 10 inputs the deterioration degree data. The deterioration degree data to be performed is acquired (step S102). The deterioration degree data is an example of the deterioration degree determination result of the beam according to the present invention.
梁の劣化度については、実物の桟橋Ｐの上部工を構成する複数の梁の各々の劣化度を、所定の判定基準に従って判定する。図５は、劣化度の判定に用いられる判定基準（以下、「判定基準Ｃ」という）を例示した図である。判定基準Ｃは劣化度ａ、劣化度ｂ、劣化度ｃおよび劣化度ｄがある。劣化度は、劣化度ａが最も劣化の程度が高く、劣化度ｂは劣化度ａより劣化の程度が低く、劣化度ｃは劣化度ｂより劣化の程度が低く、劣化度ｄは、変状なしというものである。図６に、評価する実物の桟橋Ｐの梁の劣化度の判定結果の一例を示す。図６に示す岸壁法線Ｌは、桟橋Ｐと陸との境界を示し、図６においては、岸壁法線Ｌに沿った方向を法線平行方向と称し、岸壁法線Ｌに直角な方向を法線直角方向と称する。 Regarding the degree of deterioration of the beams, the degree of deterioration of each of the plurality of beams constituting the superstructure of the actual pier P is determined according to a predetermined criterion. FIG. 5 is a diagram illustrating a determination criterion (hereinafter, referred to as “determination criterion C”) used for determining the degree of deterioration. Judgment criteria C include deterioration degree a, deterioration degree b, deterioration degree c, and deterioration degree d. As for the degree of deterioration, the degree of deterioration a is the highest degree of deterioration, the degree of deterioration b is lower than the degree of deterioration a, the degree of deterioration c is lower than the degree of deterioration b, and the degree of deterioration d is deformation. There is nothing. FIG. 6 shows an example of the determination result of the degree of deterioration of the beam of the actual pier P to be evaluated. The quay normal line L shown in FIG. 6 indicates the boundary between the pier P and the land. In FIG. 6, the direction along the quay normal line L is referred to as the normal parallel direction, and the direction perpendicular to the quay normal line L is defined as the normal direction. It is called the direction perpendicular to the normal.
オペレータは、劣化度データを入力し終えると、桟橋Ｐの評価を指示する操作を操作部１０４において行う。この操作が行われたコンピュータ装置１０の計算部１００２は、桟橋Ｐのモデルを構成する梁の劣化度を点数化する（ステップＳ１０３）。 When the operator finishes inputting the deterioration degree data, the operator performs an operation instructing the evaluation of the pier P in the operation unit 104. The calculation unit 1002 of the computer device 10 in which this operation is performed scores the degree of deterioration of the beams constituting the model of the pier P (step S103).
具体的には、コンピュータ装置１０は、次の式（１）を用いて劣化度から劣化度点数を算出する。
劣化度点数＝ｐ１×（劣化度ａの梁の割合）＋ｐ２×（劣化度ｂの梁の割合）＋ｐ３×（劣化度ｃの梁の割合）＋ｐ４×（劣化度ｄの梁の割合）・・・式（１）
劣化度点数は、本発明に係る上部工劣化度の一例である。
Specifically, the computer device 10 calculates the degree of deterioration score from the degree of deterioration using the following equation (1).
Deterioration score = p1 x (ratio of beams with degree of deterioration a) + p2 x (ratio of beams with degree b deterioration) + p3 x (ratio of beams with degree c deterioration) + p4 x (ratio of beams with degree d deterioration) ...・ Equation (1)
The degree of deterioration score is an example of the degree of deterioration of the superstructure according to the present invention.
ｐ１、ｐ２、ｐ３およびｐ４は、判定した劣化度に対応した点数であり、ｐ１は劣化度ａの点数を示し、ｐ２は劣化度ｂの点数を示し、ｐ３は劣化度ｃの点数を示し、ｐ４は劣化度ｄの点数を示す。ｐ１〜ｐ４は、予め定められた値であり、ｐ１〜ｐ４の大小関係は、ｐ１＞ｐ２＞ｐ３＞ｐ４となっている。 p1, p2, p3 and p4 are the scores corresponding to the determined deterioration degree, p1 indicates the deterioration degree a score, p2 indicates the deterioration degree b score, and p3 indicates the deterioration degree c score. p4 indicates the score of the degree of deterioration d. p1 to p4 are predetermined values, and the magnitude relationship of p1 to p4 is p1> p2> p3> p4.
式（１）における梁の割合については、例えば、梁の総本数が１００本であり、劣化度ａの梁の本数が３０本、劣化度ｂの梁の本数が４０本、劣化度ｃの梁の本数が１５本、劣化度ｄの梁の本数が１５本の場合、劣化度ａの梁の割合＝０．３、劣化度ｂの梁の割合＝０．４、劣化度ｄの梁の割合＝０．１５、劣化度ｄの梁の割合＝０．１５となる。 Regarding the ratio of beams in the formula (1), for example, the total number of beams is 100, the number of beams with a degree of deterioration a is 30, the number of beams with a degree of deterioration b is 40, and the number of beams with a degree of deterioration c is 40. When the number of beams is 15 and the number of beams with a degree of deterioration d is 15, the ratio of beams with a degree of deterioration a = 0.3, the ratio of beams with a degree of deterioration b = 0.4, and the ratio of beams with a degree of deterioration d = 0.15, and the ratio of beams having a degree of deterioration d = 0.15.
次にコンピュータ装置１０の計算部１００２は、桟橋Ｐが直杭式横桟橋の場合（ステップＳ１０４でＹＥＳ）、桟橋Ｐのモデルの梁の各々について補正係数を設定する（ステップＳ１０５）。海側に配置された梁と陸側に配置された梁では、同じ劣化度であっても桟橋Ｐ全体に与える影響が異なる。そこで、梁配列に応じて補正係数を設定する。例えば、法線平行方向に沿った梁について、陸からの位置に応じて補正係数を設定する。法線平行方向に沿った梁が５列ある桟橋Ｐの場合、図７に示すように、海側から１列目の梁に補正係数ａ１を設定し、海側から２列目の梁に補正係数ａ２を設定し、海側から３列目の梁に補正係数ａ３を設定し、海側から４列目の梁に補正係数ａ４を設定し、海側から５列目の梁に補正係数ａ５を設定する。即ち、本発明においては、法線平行方向に沿った梁の列に応じてグループを形成し、同一のグループに属する梁に対しては、グループ固有の補正係数を設定している。 Next, when the pier P is a straight pile type horizontal pier (YES in step S104), the calculation unit 1002 of the computer device 10 sets a correction coefficient for each of the beams of the model of the pier P (step S105). The beam arranged on the sea side and the beam arranged on the land side have different effects on the entire pier P even if the degree of deterioration is the same. Therefore, the correction coefficient is set according to the beam arrangement. For example, for a beam along the normal parallel direction, a correction coefficient is set according to the position from the land. In the case of a pier P having five rows of beams along the normal parallel direction, as shown in FIG. 7, a correction coefficient a1 is set for the beam in the first row from the sea side, and the beam is corrected to the beam in the second row from the sea side. The coefficient a2 is set, the correction coefficient a3 is set for the beam in the third row from the sea side, the correction coefficient a4 is set for the beam in the fourth row from the sea side, and the correction coefficient a5 is set for the beam in the fifth row from the sea side. To set. That is, in the present invention, a group is formed according to a row of beams along the normal parallel direction, and a group-specific correction coefficient is set for beams belonging to the same group.
また、法線直角方向に沿った梁について、陸からの位置に応じて補正係数を設定する。法線直角方向に沿った梁が４列ある桟橋Ｐの場合、図７に示すように、海側の梁からそれぞれ補正係数ａａ１、補正係数ａａ２、補正係数ａａ３、補正係数ａａ４を設定する。即ち、本発明においては、法線直角方向に沿った梁の列に応じてグループを形成し、同一のグループに属する梁に対しては、グループ固有の補正係数を設定している。 In addition, for beams along the direction perpendicular to the normal line, a correction coefficient is set according to the position from the land. In the case of the pier P having four rows of beams along the normal direction, the correction coefficient aa1, the correction coefficient aa2, the correction coefficient aa3, and the correction coefficient aa4 are set from the beams on the sea side, respectively, as shown in FIG. That is, in the present invention, groups are formed according to the rows of beams along the direction perpendicular to the normal line, and group-specific correction coefficients are set for beams belonging to the same group.
また、法線平行方向に沿った梁と法線直角方向に沿った梁では、同じ劣化度であっても、その方向によって桟橋Ｐ全体に与える影響が異なる。そこで、梁の方向に応じて補正係数を設定する。具体的には、法線平行方向に沿った梁について、陸からの位置に応じて補正係数を設定する。例えば、図８に示すように、法線平行方向に沿った梁のそれぞれについて補正係数ｂ１を設定し、法線直角方向に沿った梁のそれぞれについて補正係数ｂ２を設定する。即ち、本発明においては、梁向きに応じてグループを形成し、同一のグループに属する梁に対しては、グループ固有の補正係数を設定している。 Further, the beam along the normal parallel direction and the beam along the normal perpendicular direction have different effects on the entire pier P depending on the direction even if the degree of deterioration is the same. Therefore, the correction coefficient is set according to the direction of the beam. Specifically, the correction coefficient is set according to the position from the land for the beam along the normal parallel direction. For example, as shown in FIG. 8, a correction coefficient b1 is set for each of the beams along the normal parallel direction, and a correction coefficient b2 is set for each of the beams along the normal perpendicular direction. That is, in the present invention, groups are formed according to the beam orientation, and group-specific correction coefficients are set for beams belonging to the same group.

［変形例］
上述した実施形態は様々に変形することができる。以下にそれらの変形の例を示す。なお、上述した実施形態及び以下に示す変形例は適宜組み合わされてもよい。
[Modification example]
The above-described embodiment can be modified in various ways. Examples of these modifications are shown below. In addition, the above-described embodiment and the following modifications may be combined as appropriate.
（１）本発明においては、桟橋の一部の区域について、ステップＳ１０１でモデルを作成し、当該区域の梁の劣化度の判定結果をステップＳ１０２で入力することにより、桟橋の一部の区域について損傷の構造解析結果と損傷度を出力してもよい。 (1) In the present invention, a model is created in step S101 for a part of the pier, and the determination result of the degree of deterioration of the beam in the area is input in step S102 for the part of the pier. The result of structural analysis of the damage and the degree of damage may be output.
（２）上述した実施形態においては、データベースＤＢ１において、有害ひび割れ領域の割合、降伏領域の割合、終局領域の割合を構造解析結果として格納し、この割合をディスプレイ１０３で出力しているが、ステップＳ１０１で生成したモデルと、格納されている割合から各領域の面積を算出し、算出した面積を出力してもよい。 (2) In the above-described embodiment, the database DB1 stores the ratio of the harmful cracked area, the ratio of the yield area, and the ratio of the final area as the structural analysis result, and outputs this ratio on the display 103. The area of each area may be calculated from the model generated in S101 and the stored ratio, and the calculated area may be output.
（３）桟橋の損傷に係る情報の出力については、経年劣化を考慮した将来の時点における桟橋Ｐに対して外力が加えられた後の損傷に係る情報を出力してもよい。図９は、将来の時点における桟橋Ｐに対して外力が加えられた後の損傷に係る情報を出力する処理の流れを示したフローチャートである。 (3) Regarding the output of information on damage to the pier, information on damage after an external force is applied to the pier P at a future time in consideration of aging deterioration may be output. FIG. 9 is a flowchart showing a flow of processing for outputting information relating to damage after an external force is applied to the pier P at a future time point.
まず、オペレータは、損傷を評価する実物の桟橋Ｐについて設計図を参照し、桟橋Ｐの梁を仮想的に表すモデルを作成する操作を操作部１０４で行う。コンピュータ装置１０は、オペレータが行った操作に応じて桟橋Ｐのモデルを生成する（ステップＳ２０１）。 First, the operator refers to the design drawing of the actual pier P for evaluating damage, and the operation unit 104 performs an operation of creating a model that virtually represents the beam of the pier P. The computer device 10 generates a model of the pier P according to the operation performed by the operator (step S201).
次にオペレータは、時点ｔ０における桟橋Ｐの複数の梁の各々の劣化度を示す劣化度データを操作部１０４から入力し、コンピュータ装置１０のデータ取得部１００１は、入力される劣化度データを取得する（ステップＳ２０２）。また、オペレータは、時点ｔ０より後の時点ｔ１における桟橋Ｐの複数の梁の各々の劣化度を示す劣化度データを操作部１０４から入力し、コンピュータ装置１０のデータ取得部１００１は、入力される劣化度データを取得する（ステップＳ２０３）。なお、時点ｔ０は例えば桟橋Ｐの建設時点としてもよい。時点ｔ０を桟橋Ｐの建設時点とする場合、時点ｔ０における梁の劣化度は全て劣化度ｄであることが自明のため、仮に時点ｔ１より過去に梁の目視点検等が１度も行われていなくても、本変形例は実施可能である。 Next, the operator inputs the deterioration degree data indicating the deterioration degree of each of the plurality of beams of the pier P at the time point t0 from the operation unit 104, and the data acquisition unit 1001 of the computer device 10 acquires the input deterioration degree data. (Step S202). Further, the operator inputs the deterioration degree data indicating the deterioration degree of each of the plurality of beams of the pier P at the time point t1 after the time point t0 from the operation unit 104, and the data acquisition unit 1001 of the computer device 10 is input. Acquire deterioration degree data (step S203). The time point t0 may be, for example, the time point at which the pier P is constructed. When the time point t0 is the time of construction of the pier P, it is obvious that the degree of deterioration of the beam at the time point t0 is all the degree of deterioration d. Therefore, the beam has been visually inspected even once before the time point t1. This modification can be carried out without it.
オペレータは、時点ｔ０から時点ｔ１までの時間を示す時間データおよび時点ｔ１から時点ｔ１より後の任意時点である時点ｔ２までの時間を示す時間データを操作部１０４から入力し、コンピュータ装置１０は、入力された時間データを取得する（ステップＳ２０４）。時間データを取得したコンピュータ装置１０は、取得した劣化度データと時間データを、予め準備された確率モデルに入力し、時点ｔ２における各梁の劣化度を将来予測の確率モデルにより推定する（ステップＳ２０５）。なお、ここで用いられる確率モデルは、過去の状態推移に基づく確率により将来の状態推移を推定するモデルであれば、いずれのモデルであってもよい。そのようなモデルの一例として、マルコフ連鎖モデルが挙げられる。 The operator inputs time data indicating the time from the time point t0 to the time point t1 and time data indicating the time from the time point t1 to the time point t2 which is an arbitrary time point after the time point t1 from the operation unit 104, and the computer device 10 inputs the time data. Acquire the input time data (step S204). The computer device 10 that has acquired the time data inputs the acquired deterioration degree data and the time data into a probability model prepared in advance, and estimates the deterioration degree of each beam at the time point t2 by the probability model of future prediction (step S205). ). The probabilistic model used here may be any model as long as it is a model that estimates future state transitions based on probabilities based on past state transitions. An example of such a model is a Markov chain model.
コンピュータ装置１０は、上記のように推定した時点ｔ２における劣化度を用いて、ステップＳ２０６〜ステップＳ２１１の処理を行う。ステップＳ２０６〜ステップＳ２１１の処理は、ステップＳ１０３〜ステップＳ１０８の処理と同じであるため、その説明を省略する。本変形例によれば、将来の時点ｔ２において外力が桟橋Ｐに加えられた後の桟橋Ｐの損傷に係る情報を得ることができる。 The computer device 10 performs the processes of steps S206 to S211 using the degree of deterioration at the time point t2 estimated as described above. Since the processing of steps S206 to S211 is the same as the processing of steps S103 to S108, the description thereof will be omitted. According to this modification, it is possible to obtain information on damage to the pier P after an external force is applied to the pier P at a future time point t2.
