Example Embodiment

[0026] Example

[0027] Such as figure 1 As shown, the health status and maintenance cost estimation method of roads, bridges and tunnels based on Markov model; the steps are as follows:

[0028] Step 1. Use computer software to evaluate the health status based on the historical data of the road, bridge or tunnel to be tested, and calculate the individual health indicators and maintenance costs of each road, bridge or tunnel to be tested;

[0029] Step 2: Use a computer to perform regression analysis on individual health indicators and maintenance costs of highways, bridges or tunnels through regression analysis methods, and calculate the corresponding maintenance costs under different health indicators;

[0030] Step 3: Calculate the state transition probability vector, and use the Markov model to measure the health indicators of the road, bridge or tunnel;

[0031] Step 4. Calculate maintenance costs based on health indicators.

[0032] In practical applications, the deterioration of ...

Abstract

The invention discloses a road, bridge and tunnel health state and maintenance cost measuring and calculating method based on a Markov model. The method comprises the following steps: step 1, evaluating a health state through computer software according to historical data of roads, bridges or tunnels to be tested, and calculating a single health index and maintenance cost of each road, bridge or tunnel to be tested; step 2, conducting regression analysis on the single health indexes and the maintenance cost of the highway or the bridge or the tunnel through a regression analysis method by means of a computer, and calculating the maintenance cost corresponding to different health state indexes; step 3, calculating a state transition probability vector, and measuring and calculating health state indexes of a road, a bridge or a tunnel by utilizing a Markov model; and step 4, measuring and calculating the maintenance cost based on the health state indexes. According to the invention, on the premise of greatly reducing manpower investment, the accuracy of road, bridge and tunnel health state and maintenance cost measurement and calculation can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of computer-aided road, bridge and tunnel evaluation, in particular to a Markov model-based method for measuring and calculating the health status and maintenance cost of road, bridge and tunnel. Background technique [0002] The health status and maintenance cost estimation of highways, bridges and tunnels has always been an important basis for decision-making of highways, tunnels and bridges maintenance. [0003] Accurate health status measurement and maintenance cost estimation are helpful for maintenance planning and reasonable allocation of maintenance budget. Health status indicators are an important basis for reflecting highways, bridges, and tunnels. Different individual indicators can reflect the safety and performance of structures in different aspects. Through the measurement and calculation of the current and future health status indicators of roads, bridges, and tunnels, it helps us judge when ...
