(2−1−1)要因(1)の判断基準
点検項目a〜fは、「危険」、「注意」、「安全」の3項目に分かれており、使用者が盛土構造物を視認・測定等し、表2に記載の判断項目に照らして3項目のうち何れか1つを選択する。
(2-1-1) Judgment criteria for factor (1) The inspection items a to f are divided into three items of “danger”, “caution”, and “safety”, and the user visually recognizes and measures the embankment structure.

図3は、盛土構造物を橋台やボックスカルバートなどの構造物の巻き込み部として適用していた場合の判断フローを示す図である。構造物の巻き込み部は、盛土構造物の変状が路面に与える影響が小さいため、軽微な補修で終わることが多い。したがって、初期判断は、評価要素(d)の路面の段差が管理基準値が安全領域である限り、総合評価の上限を注意とするように、図2に記載の判断フローよりも判断基準を緩和させてある。   FIG. 3 is a diagram illustrating a determination flow in the case where the embankment structure is applied as an entrainment portion of a structure such as an abutment or a box culvert. Since the influence of the deformation of the embankment structure on the road surface is small, the entrainment part of the structure often ends with minor repairs. Therefore, the initial judgment is more relaxed than the judgment flow shown in FIG. 2 so that the upper level of the comprehensive evaluation is noted as long as the road level difference of the evaluation element (d) is the safe standard. I'm allowed.

なお、前記評価要素項目の種類、又は評価式の種類は、盛土構造物の種類や、設置場所等によって異なるようにデータベース化しておいてもよいし、使用者からのフィードバックによって適宜変更可能に構成しておいてもよい。   The type of the evaluation element item or the type of the evaluation formula may be stored in a database so as to differ depending on the type of the embankment structure, the installation location, etc., or can be appropriately changed by feedback from the user. You may keep it.

The data acquisition unit 12 has a function of generating a screen (disaster prevention chart) for inputting an evaluation element to be input by the user and displaying the screen on the display device 3.
First, the data acquisition means 12 generates and displays a screen that prompts the user to input data such as the type of embankment structure and the installation location.
Next, when the user inputs data such as the type of the embankment structure and the installation location, the evaluation element item based on the data is acquired from the storage unit 11 and a data input screen based on the evaluation element item is generated. Then, it is displayed on the display device 3 and prompts the user to input an evaluation element.

(5)表示手段14
表示手段14は、前記判定手段13で算出された安定性情報を、表示装置3に表示する機能を有する。例えば、「安全」「注意」「危険」の表示を色分けすること等によって視覚的に理解しやすいように表示しても良い。
(5) Display means 14
The display unit 14 has a function of displaying the stability information calculated by the determination unit 13 on the display device 3. For example, the display of “safe”, “caution”, and “danger” may be displayed so as to be easily understood visually by color coding.

以上説明したとおり、本実施例によれば、盛土構造物の変状をとらえるための要素を予め決定しておくことにより点検者による判断のばらつきが無くなり、また必ずしも高度な知見をもった専門技術者で無くても安定性評価が可能となる。また、盛土構造物の変状をとらえるための要素、因果関係、判断フロー、重み付けを適宜変更することにより、より精度の高い安定性評価を行うことができる。   As explained above, according to the present embodiment, by determining in advance the elements for catching the deformation of the embankment structure, there is no variation in judgment by the inspector, and it is not necessarily a specialized technique with advanced knowledge. Even if you are not a person, you can evaluate stability. Moreover, more accurate stability evaluation can be performed by appropriately changing the elements, the causal relationship, the judgment flow, and the weights for detecting the deformation of the embankment structure.

また、本願発明は、先の実施例1に記載の表示手段14を以下のように構成することもできる。   In the present invention, the display means 14 described in the first embodiment can also be configured as follows.

(1)総合評価図表の作成
表示手段14では、判定手段13から得られる盛土構造物の安定性情報を二次元座標上に図表化して表示することもできる。
図表化にあたっては、先の実施例1で説明した評価フロー(図2,図3)を定式化し、さらに各評価要素を数値化しておくことを前提とする。
そして、各要素を種々組み合わせて加算した指標に基づき、二次元座標内にプロットし、当該プロットした箇所が、二次元座標のどの領域内の属しているかによって、盛土構造物の状態を視覚的に表示することができる。
(1) Creation of Comprehensive Evaluation Chart The display means 14 can also display the stability information of the embankment structure obtained from the determination means 13 on a two-dimensional coordinate chart.
In the charting, it is assumed that the evaluation flow (FIGS. 2 and 3) described in the first embodiment is formulated, and that each evaluation element is further quantified.
Then, based on an index obtained by adding various combinations of the respective elements, the plot is plotted in two-dimensional coordinates, and the state of the embankment structure is visually determined depending on which region of the two-dimensional coordinates the plotted location belongs to. Can be displayed.

図4に、安定性情報を図表化する場合の一例を示す。
二次元座標中には、「安全」「注意」「危険」の各領域が予め区分けして設定されている。
各軸における指標1〜3は、先の表かフローの定式化、評価要素の数値化によって各要因毎に設定された数値を加算して合計した数値であり、例えば以下のように定義することができる。
[指標1]前記要因(1)の評価を合計した数値(盛土構造物及び周辺の変状を表す変数)
[指標2]要因(1)と要因(2)の評価を合計した数値(地形的要因による盛土構造物の変状を表す変数)
[指標3]要因(1)と要因(3)の評価を合計した数値(機能的要因による盛土構造物の変状を表す変数)
FIG. 4 shows an example when the stability information is charted.
In the two-dimensional coordinates, areas of “safety”, “caution”, and “danger” are set in advance.
Indicators 1 to 3 on each axis are the sum of the values set for each factor in the previous table or flow formulation and evaluation element quantification. For example, define as follows: Can do.
[Indicator 1] A numerical value obtained by summing up the evaluations of the above factor (1) (a variable indicating the embankment structure and surrounding deformation).
[Indicator 2] A numerical value summing up the evaluation of factor (1) and factor (2) (variable representing the deformation of the embankment structure due to topographic factors)
[Indicator 3] A numerical value that sums up the evaluations of factor (1) and factor (3) (variables representing deformation of embankment structure due to functional factors)

(2)図表化方法
まず、前記二次元座標の横軸に指標1の数値を設定する。
次に、前記二次元座標の縦軸の一方(図2における左側)に指標2の数値を設定する。
次に、前記二次元座標の縦軸の他方(図2における右側)に指標3の数値を設定し、
そして、前記指標2と指標3とを結ぶ直線と、指標1の垂線との交点をとり、当該交点が何れの領域内にあるかによって、盛土構造物の安定性情報を視覚的に表示することができる。
(2) Charting Method First, the numerical value of index 1 is set on the horizontal axis of the two-dimensional coordinate.
Next, the numerical value of the index 2 is set on one of the vertical axes of the two-dimensional coordinates (left side in FIG. 2).
Next, the numerical value of the index 3 is set on the other (right side in FIG. 2) of the vertical axis of the two-dimensional coordinates,
Then, the intersection of the straight line connecting the index 2 and the index 3 and the perpendicular of the index 1 is taken, and the stability information of the embankment structure is visually displayed depending on which region the intersection is in. Can do.

本実施例によれば、要因2(地形的要因)と要因3(機能的要因)とを数値化するに際し、重み付けを行うことによって、盛土構造物及び周辺の変状、地形的要因、及び機能的要因のどの要因がどの程度安定性評価に影響を与えているのかを、視覚的に判断することができる。
例えば、指標2(要因1と要因2の和(地形的要因))がある程度危険領域として判断される場合であっても、要因3(要因1と要因3の和(機能的要因))における危険性が多少低いと判断される場合には、指標2と3を結ぶ直線は右肩さがりとなり、指標1からの垂線との交点が図に示すように注意領域にプロットされる場合が生じることとなる。
一方、指標2では注意領域として判断される場合であっても、要因3において危険性が高いと判断される場合には、指標2と3を結ぶ直線は右肩あがりとなり、指標1からの垂線との交点が危険領域にプロットされる場合が生じることとなる。
According to the present embodiment, when the factor 2 (topographic factor) and the factor 3 (functional factor) are quantified, weighting is performed so that the embankment structure and the surrounding deformation, the topographic factor, and the function It is possible to visually determine which factor of the mechanical factor affects the stability evaluation.
For example, even if indicator 2 (the sum of factor 1 and factor 2 (topographical factor)) is determined to be somewhat dangerous, the risk in factor 3 (the sum of factor 1 and factor 3 (functional factor)) If it is determined that the characteristics are somewhat low, the straight line connecting the indexes 2 and 3 becomes a right shoulder, and the intersection with the perpendicular from the index 1 may be plotted in the attention area as shown in the figure. Become.
On the other hand, even if the index 2 is determined as a caution area, if the risk is determined to be high in the factor 3, the straight line connecting the indexes 2 and 3 becomes a right shoulder, and the perpendicular from the index 1 In some cases, the intersection point with is plotted in the dangerous area.

以上説明したとおり、本実施例によれば、判定手段より得られる安定性情報から3種の指標を生成し、当該3種の指標を図表化することによってどの要因の影響をどの程度受けているのかを視覚的に把握することができる。   As described above, according to the present embodiment, three types of indicators are generated from the stability information obtained from the determination means, and the degree of influence of which factors is affected by charting the three types of indicators. Can be grasped visually.
