Based on the numerical simulation and engineering projects,this paper studied the pavement collapse of hydraulic reclamation land area in Qinzhou Free Trade Port Area and its formation mechanism by applying the detection method of ground penetrating radar(GPR).By using finite difference numerical simulation method,the authors conducted simulation trial on subgrade defects of hydraulic reclamation land area by using GPR.Then they detected the subgrade defects of Qinzhou Free Trade Port Area by using GPR,and analyzed the cause of collapse while taking the geological characteristics of the surveying area and construction technology into account.The results indicated that GPR was useful in the survey of pavement defects in hydraulic reclamation land area,which provided theoretical and practical basis for the application of GPR on detection of pavement defects in similar area.Moreover,it indicated that the genesis of pavement collapse had the particularity of the coastal hydraulic reclamation land area,and the location of the defects were prominently correlated with the distribution of underground pipelines.This provided a scientific basis for management and maintenance organizations in defect control.
