Fuzzy analytic hierarchy process for risk evaluation of collapse during construction of mountain tunnel
Liu Bao-chen · Rock and Soil Mechanics · 2009
Fuzzy analytic hierarchy process(FAHP) of risk assessment has been used in tunnel collapse;through collecting and collating information of the tunnel collapse,the major factors are summed up and selected as the impact factor of FAHP.Through analyzing the statistical materials,the membership function is proposed between the factors and the probability of occurrence of collapse and collapse volume.And a comprehensive assigning method is adopted to determine the weight of evaluation indices.Then the model of FAHP has been established and applied to Qingshangang Tunnel.The results are credible.
