TO 土老帽:
W$x K^} pO-)x:Wg 1) Before you use any software, you'd better read some theoretical
!XG/,)A %3#b6m~ books about finite element method for structure, for example the
#d7)$ub r ;@:S~ book from Tsinghua Univ. is good one.
?j},O= JFn +btP]?04 2) After you understand the FEM in structures(beam or truss),
*,Aa9wa{ <"j"h=tm} you can use some small finite element program to
55u^u F bCe[nmE2 solve beam or some structure problems for better understanding;
Qe' PAN =B [U+<uZzOC 3) Then, the next step, try to really understand all the constitutive law
v= 8~ZDY x< )!$cg in Geotechnical Engineering(Mohr-Coulomb Model, Duncan-Chang
q[We][Nrzb 5VY%o8xXa model, Hardening soil model, Cam model, and some models for
. pNq-T OP\^c rock). Actually, you may know all the soil behavior very well and all
$n_sGr A
`H]q5d the advantages and disadvantages for each model.
j$JV(fz d@`-!" 4) Finally, you can get involved in some commercial program,such as
A=@V LU4% -v/?> PLAXIS and so on (PLAXIS is better for the first user).
=qVAvo ' t 's5~ The very important thing is what's the problem you want to solve by
]c~ rPi p]J]<QaZD program? which method you like to use and which model is better
&El[ `s|\" @2 for these soil behavior.

=r@ie>* U /Wta$!X{- in-site or measured data.
E!oJ0* @ PT= 2LZ All the programs are only the tools you use to solve your problems.
