Abstract：With the continuous development of urban road networks,road collapse has become more and more serious.In order to better evaluate the susceptibility of road collapse disaster for early warning,the ground-penetrating radar(GPR)data was innovatively integrated into the evaluation system,which reflected the susceptibility of urban road collapse more intuitively.The coefficient of variation-G1 method was used for subjective and objective cross-assigning of indexes.Finally,the evaluation method of the extension cloud model was utilized,which reflected the objective law of road collapse with ambiguity and stochasticity,and a susceptibility evaluation model of urban road collapse was constructed.The scientific validity of the evaluation model was verified by taking a municipal road in Guangzhou City as an engineering example.
