ANALYSIS ON SEISMIC EFFECT FOR SATURATED SOIL USING B SPLINE FUNCTION FINITE ELEMENT
应用样条有限元方法分析饱和土体的地震效应

Applying principle of effective stress, the numerical analysis is made on the seismic effect, such as the vibration pore water pressure, displacement and stress, for saturated soil under the influence of earthquake with B spline function on the basis of Biot' consolidation theory. The calculation is made for a real example and the result is good in accordance with the usual law obtained from normal FEM.
