TO 土老帽:
q+<,FdG 'Z9UqEGV 1) Before you use any software, you'd better read some theoretical
0:4>rYBC DKem;_6OQ books about finite element method for structure, for example the
fl9VokAT j TV4iX book from Tsinghua Univ. is good one.
_?'W 30Dg Otq1CD9 2) After you understand the FEM in structures(beam or truss),
DrAIQ7Jd D8 PC;@m
you can use some small finite element program to
a j

DcM/p8da I!u=.[5zdC model, Hardening soil model, Cam model, and some models for
T\6,@7 \dE{[^.5 rock). Actually, you may know all the soil behavior very well and all

v UO[V$rx SK@ p0: The very important thing is what's the problem you want to solve by
