|
Abstract The stress in the roof of karst cave is analyzed and calculated by three-dimensional finite element method. The relation among the critical value of distance from pile foot to karst cave top，the karst cave sizes and design load of single pile can be obtained by means of multivariable linear regression method. Finally，the reliability of the regression equation is verified by engineering example.
