Study on Durability Assessment of Tunnel Lining Structures Based on Variable Fuzzy Sets
Zhu Yan-penga · Journal of Gansu Sciences · 2013
According to the multiple indexes and levels characteristic of the durability assessment of tunnel lining structures,the variable fuzzy comprehensive evaluation model was used to determine the durability levels of tunnel lining structures.The model based on variable fuzzy sets and relative deference function was able to scientifically calculate the relative membership degree and function of various intervals of the lining structure and calculate the durability assessment levels by varying the model and its parameters,and program the calculation process by using the MATLAB.By analyzing the health condition of Lanzhou Qidaoliang tunnels lining structure on the basis of the measured data and comparing the data with the result of the fuzzy comprehensive evaluation method,the practicability of the mode was verified.This method was then applied to the durability assessment of Lanzhou Beihuan Road,and Jiuzhou Tunnel.
