GREEN FUNCTION ON TWO-PHASE SATURATED MEDIUM BY CONCENTRATED FORCE IN TWO-DIMENSIONAL DISPLACEMENT FIELD

The Green function on two-phase saturated medium by concentrated force has a broad and important use in seismology, seismic engineering, soil mechanics, geophysics, dynamic foundation theory and so on. According to the Green function on two-phase saturated medium by concentrated force in three-dimentional displacement field obtained by Ding Bo-yang et al.,it gives out the Green function in two-dimensional displacement field by infinite integral method along x 3 direction derived by De Hoop and Manolis. The method adopted in the thesis is simpler.The result will be simplified to the boundary element method of dynamic problem.
