请教:
FLAC中调用BEAM子程序,在设置起始点跟终点时,为何互换位置是一样的效果(都只对上部加衬砌,下部完全不行)
望指点指点!谢谢先!
具体命令如下:
grid 20 30
mod mohr
prop bulk 1e8 shear 3e7 fric 35 coh 1e3 tens 1e3
gen arch 10 10 14 10 180
gen arch 10 10 14 10 -180
mod null region 9 9
struct prop 2 a 0.8 i 0.04 e 4e9 dens 2500
struct beam begin grid 15 11 end grid 19 12 seg 1 prop 2
call beam.fis
set ib 15 jb 11 ie 7 je 11
set nprop 2
beam
