摘要：

The rock-socketed pile is modelled by the finite element method (FEM), while the behavior of soil and rock mass is represented by applying the boundary element method (BEM). By using the consolidation solution of layered saturated foundation as the kernel function of the BEM, the flexibility matrix for soil and rock mass is deduced. With the aid of force equilibrium and displacement continuity condition at pile-soil-rock mass interface, the pile-soil-rock mass interaction problem is solved by compiling a MATLAB program. The solutions obtained by the present theory agree well with those from existing solutions and ABAQUS. Some examples are presented to reveal the effect of socketed length, the ratio of pile-rock mass modulus, length-diameter ratio and the stratification of the socketed rock mass on the load-deformation characteristic of rock-socketed pile in multilayered transversely isotropic saturated media.
