[Aging level evaluation system 100 of facility 200]

1A and 1B are diagrams for explaining a method for evaluating the aging level of a facility, and FIG. 2 is a detailed configuration diagram of a system for evaluating the aging level of a facility according to an embodiment of the present invention.

First, as shown in FIG. 1A, according to the conventional technology, the accurate evaluation is not made by evaluating the degree of aging of a facility only according to the number of public years calculated during design.

Therefore, the aging level evaluation system 100 of a facility according to an embodiment of the present invention, as shown in Figure 1b, the aging degree of the facility including bridges, tunnels, retaining walls, buildings is not aging based on the existing public years. By evaluating through the level evaluation method, the degree of aging of a facility can be more accurately evaluated.

Specifically, in the system for evaluating the aging level of a facility according to an embodiment of the present invention, after collecting the detailed indicator measurement values by measuring the detailed indicators of the facility, the aging degree of each member and the detail indicator weight and the aging acceleration index (AAI) After calculating the comprehensive aging degree, the relative aging level of the facility can be evaluated by comparing the calculated value of the comprehensive aging degree with the actual number of public years of the facility. For example, the aging level of a facility can be evaluated by comparing the calculated aging degree of the facility with the design life, and comparing with the aging number of years and the public year of the facility at the time of evaluation.

Referring to FIG. 2, the system for evaluating the aging level of facilities according to an embodiment of the present invention is a system for evaluating the aging level of facilities 200 including bridges, tunnels, retaining walls, and buildings, and data related to aging. Collection unit 110, aging-related data analysis unit 120, detailed indicator weight setting unit 130, detailed indicator aging acceleration index setting unit 140, aging degree calculation unit for each member 150, weight setting unit for each member 160, a comprehensive aging degree calculation unit 170, an aging training and level evaluation unit 180 and an aging-related DB 190.

The aging-related data collection unit 110 includes members 210, 220, and 230 related to deterioration or damage, such as deterioration of material properties and functions, over time with respect to facilities 200 for evaluating the deteriorated level. ) Collects data related to aging of the facility 200 through the measurement of detailed indicator items.

At this time, the detailed index items include, but are not limited to, the neutralization depth of concrete, the surface strength of concrete, the crack width of concrete, the deflection of members, and the slope of members. In addition, the measurement of detailed indicator items can be carried out through the measurement method specified in "Detailed Guidelines for Safety Inspection and Precision Safety Diagnosis".

The aging-related data analysis unit 120 determines the deteriorated level of the measured value of the detailed indicator in consideration of the initial state (design value) and the limit state of the material and member by measuring the measured detailed index value obtained through the measurement of the detailed index item. Analyze. Here, the aging related DB 190 stores the initial state (design value) and the limit state of the material and member, and also stores the set weight and the aging acceleration index.

Specifically, in the case of materials, the limit state is the maximum value of deterioration or damage according to the theoretical or experimental results, and in the case of the member, the limit state is the maximum value of the allowable value reflected in the design. For example, when the detailed indicator items are specified in the "Safety Inspection and Detailed Guidelines for Precision Safety Diagnosis", the lowest rating criteria (D-class or E-class) of the evaluation method can be applied as a limit.

Here, when the measured value of the detailed indicator obtained through the measurement of the detailed indicator item has the same value as the initial state (design value), the aging level is regarded as "0" and the aging level is evaluated as "0 (Zero)". In addition, when the measured value of the detailed indicator is the same as the limit state, the aging level is regarded as the maximum, and the aging level is evaluated as “100”.

For example, when the detailed indicator is "depth of neutralization of concrete", the initial state is "0 mm", and the limit state is "depth of coated concrete (mm)". At this time, the detailed index measurement value obtained by measuring the "neutralization depth of concrete" through measurement may be expressed as the depth of the neutralized concrete from the concrete surface (mm). Accordingly, the aging level (aging degree) for each measurement item may be expressed as Equation 1 below by converting the detailed index measurement value to a relative value in the range of the initial state and the limit state. Hereinafter, the level of aging refers to the same term as deterioration.

FIG. 3 is a view illustrating calculating concrete neutralization aging as an aging level for each measurement item in a facility aging level evaluation system according to an embodiment of the present invention.

For example, as shown in FIG. 3, when the measured value of “concrete neutralization depth” in a concrete covering of 40 mm is 10 mm, the “concrete neutralization” aging degree for the corresponding member of the aging level evaluation facility is as follows. It can be calculated as in Equation 2.

FIG. 4 is a diagram illustrating calculating the surface strength of concrete as the aging level for each measurement item in the facility aging level evaluation system according to an embodiment of the present invention.

In addition, as shown in FIG. 4, when the surface strength measurement value is 26 MPa for concrete having a design reference strength of 28 MPa, the “concrete surface strength” aging degree in the corresponding member can be calculated as in Equation 3 below.

Here, 85% of the initial state of 28MPa is applied as the limit state.

Referring back to FIG. 2, the detailed indicator weight setting unit 130 sets the weight for the detailed indicator, and the detailed indicator aging acceleration index setting unit 140 sets the aging acceleration index for the detailed indicator.

The aging degree calculating unit 150 for each member calculates the aging degree for each member of the facility 200 for evaluating aging level through the analysis of detailed indicator measurement values according to the detailed index weight and the detailed index aging acceleration index.

The detailed indicator "AAI" calculates the measured values of the collected detailed indicators periodically according to the measurement period. For example, Pier Deterioration:

It is a diagram illustrating the "old age" model and weights.

If the measured values of the detailed indicators periodically collected from the facility 200 are shown, it is as shown in FIGS. 5, 7 and 9.

Calculate the old age using the measured values of the detailed indicators of the facility and through the old age according to the time (number of years or time of measurement), the detailed indicators as shown in FIGS. 6, 8, and 10 "years of public use (time)- "Old age" can also be correlated. At this time, the area of the blue hatched portion between the curve and the X-axis of the "public year (time)-aging" correlation model is calculated.

The total sum of the areas (blue hatched areas) of the sub-index “years of age (time)-aging” in the member is 100, and the weight is determined by the size of the area of each sub-index. Accordingly, the larger the size of the area (blue hatched portion), the larger the weight, and the smaller the size of the area, the smaller the weight.

Referring again to FIG. 2, the weight setting unit 160 for each member sets the weight for the member, and when calculating the age of each member, the member 200 is absent depending on the type and characteristics of the members 210 to 230 (210~230) is classified, and the data of the measured values of detailed indicators related to the aging of each member (210-230) is combined to calculate the aging of the corresponding member (210-230).

5 to 10, when three detailed indicators are considered in order to calculate the aging of the pier member, the weight can be determined by the ratio of the area of each detailed indicator to the sum of the areas of the three detailed indicators. .

For example, the concrete neutralization aging weight (CNDW) is given by Equation 6 below, and the concrete surface strength aging weight (CSSDW) is given by Equation 7 below, and the bridge slope aging weight (PGDW) ) Is given by Equation 8 below.

Referring to FIG. 2 again, the comprehensive aging calculation unit 170 calculates the results of calculating the aging for each member of the facility and the weight for each member. That is, the overall aging degree for the facility 200 is calculated by multiplying the aging degree for each member and the weight for each member, and adding the calculated values for each member. At this time, the weight for each member of the facility 200 may be applied to the weight for each member specified in the "Safety Inspection and Detailed Safety Diagnosis Detailed Guidelines".

(교각 가중치) + (바닥판 노후도)

(바닥판 가중치) + … + (기초 노후도)

(Bridge weight) + (Bottom plate aging)

(Bottom weight) +… + (Basic old age)

(Basic weight)}

It can be given at 100%.

Accordingly, when the aging degree of each member and the weight of each member are as shown in Table 1, the overall aging of the bridge can be calculated as 23.54%. Here, the member of the first bridge may be a bottom plate, a shift/bridge, a foundation, a bridge support, a telescopic joint, a bridge packaging, a drainage facility, a protection facility, but is not limited thereto.

Referring again to FIG. 2, the aging training and level evaluation unit 180 may evaluate the aging level of the facility through a relative comparison between the calculated total aging degree value and the actual public years of the facility.

At this time, the overall aging degree of the facility is derived as a constant value between 0 and 100%, and the overall aging degree 0% can be seen immediately after the completion of aging, and the overall aging degree 100% has reached the limit of aging. As a case, it can be regarded as the design life considered at the time of design.

Accordingly, the overall aging of the calculated facilities can be compared with the design life to be expressed as "facilities aging years", and the calculated "age aging years" are compared with the public years of the facilities at the time of evaluation. Level".

For example, if the design life of the first bridge is 40 years, the public year at the time of evaluation is 12 years, and the overall aging is 23.54%, the facility aging training for the first bridge is calculated as shown in Equation 11 below. can do.

After all, the number of public years of the first bridge is 12 years, but the age of aging is estimated to be 9.416 years.

In addition, for example, when the design life of the first bridge is 100 years, the public years at the time of evaluation is 25 years, and the overall aging is 23.54%, the aging level of the first bridge is as shown in Equation 12 below. Can be calculated.

At this time, if the calculation result is less than 1, the level of aging is lower than the number of public years, and if it is greater than 1, it means that the level of aging is higher than the number of public years.

In the end, in the case of the facility aging level evaluation system 100 according to an embodiment of the present invention, the degree of aging of the facilities including bridges, tunnels, retaining walls, and buildings is evaluated based on the measurement data of the facilities, not on the basis of public years. By calculating through the method, it is possible to more accurately evaluate the degree of aging of a facility, and also by setting the weights for the detailed items of facilities and the accelerated aging of detailed indicators, and calculating the aging and comprehensive aging for each member, The actual level of aging can be assessed through relative comparisons between public years.

[Method for evaluating aging level of facility 200]

11 is an operation flow diagram of a method for evaluating the aging level of a facility according to an embodiment of the present invention.

Referring to FIG. 11, in the method for evaluating the aging level of a facility according to an embodiment of the present invention, first, detailed index items for the facility 200 for evaluating the aging level are measured (S110). Here, the detailed index items include, but are not limited to, the neutralization depth of concrete, the surface strength of concrete, the crack width of concrete, the deflection of members, and the slope of members. In addition, the measurement of detailed indicator items can be carried out through the measurement method specified in "Detailed Guidelines for Safety Inspection and Precision Safety Diagnosis".

Next, aging-related data measured through the measurement of the detailed indicators are collected (S120). That is, the measurement of detailed index items of members 210, 220, and 230 related to deterioration or damage, such as deterioration of material properties and functions, over time for a facility 200 for evaluating the deteriorated level. Obtain data related to aging of the facility 200 through.

Next, the aging related data, which are the measured values of the detailed indicators, are analyzed according to the initial state and the limit state of the materials and members of the facility (S130). At this time, the aging level (aging degree) for each measurement item may be analyzed by converting the measured values of the detailed indicators into relative values in the range of the initial state and the limit state.

Next, the aging degree for each member is calculated in consideration of the weight of the detailed indicator and the acceleration index of the aging of the detailed indicator (S140). For example, the metric weight and the aging acceleration index are set, and the aging degree of each member of the aging level evaluation facility 200 is multiplied by the respective metric measurement data and the corresponding metric weight and the metric acceleration index. , It is calculated as the sum of all detailed indicators in the members 210 to 230 calculated as described above.

Next, the overall aging degree of the facilities is calculated by synthesizing the aging degree for each member (S150). At this time, the overall aging degree for the facility 200 is calculated through the results of calculating the aging degree for each member of the facility and the weight for each member, multiplied by the age for each member and the weight for each member, and calculated by adding the calculated value for each member. . At this time, the weight for each member of the facility 200 may be applied to the weight for each member specified in the "Safety Inspection and Detailed Safety Diagnosis Detailed Guidelines".

Next, the aging level of the facility is evaluated through a relative comparison between the calculated total aging degree value and the actual public years of the facility (S160). At this time, the overall aging degree of the facility is derived as a constant value between 0 and 100%, and the overall aging degree 0% can be seen immediately after the completion of aging, and the overall aging degree 100% has reached the limit of aging. As a case, it can be regarded as the design life considered at the time of design.

Accordingly, the overall aging degree of the calculated facility is compared with the design life, and expressed as aging years, and the aging years and the aging level can be evaluated by comparing the aging years with the public years of the facilities at the time of evaluation.

After all, according to the embodiment of the present invention, it is possible to establish a maintenance plan according to the aging level of the facility, and it can be used as a basic data for analyzing the cause of facility aging and preparing measures.
