我刚学FLAC3D,在做一个沉降的题。可是后面输出来的displacement里有些点x方向也有位移,实在找不出来哪里出错了。麻烦大家帮我看一下
基础做均布荷载算宽5m,网格51m,上面可压缩性土E=4MPa;下面岩石,E=100GPa。都是水平的。可压缩层2.5m,下面我定的10m。密度没给,我上网查的平均值
我是这么写的:
new
generate zone brick size 51 1 10 &
dimension 51 1 10 group 1
generate zone brick size 51 1 3 &
p0 0 0 10 &
dimension 51 1 2.5
model elastic
property bulk 4e6 range group 1
property bulk 1e11 range group 1 not
set grav 0 0 -9.8
initial dens 1800 range group 1
initial dens 2650 range group not
fix x ran x 0
fix x ran x 51
fix y ran y 0
fix y ran y 1
fix z ran z 0
apply szz -3e4 range z=12.4 12.6 x=23 28 y=0 1
hist id=1 gp zdis 23 0.5 12.5
hist id=2 gp zdis 25 0.5 12.5
hist id=3 gp zdis 28 0.5 12.5
solve
save 0.5.sav
不知道哪里有问题哇
