本人初学者,在建立复合地基模型时发现问题,想求教在计算初始应力场时,什么情况下应该设置边界初始应力?初始应力大小怎么确定?附模型计算命令流(只建立了垫层跟地基土):

gen zone brick p0 (0,0,0) p1 (36,0,0) p2 (0,36,0) p3 (0,0,20) & size 36 36 20

fix y ran y -0.1 0.1
fix y ran y 119.9 120.1
set grav 0 0 -10
solve
gen separate soil
Create interface elements on the cushion surface of the soil
interface 1 wrap soil cushion
plot create view_int
plot add surface
plot add interface red
plot show
save int.sav
求高手指教! |
