FLAC2d gen line绘制地表和岩层界限问题
昨天用flac2d做一个边坡的稳定性分析，出现一个问题，就是用gen line命令绘制地表线和岩层界限时，线不连贯，无法切割模型，请教下这是怎么回事，如何解决，命令流如下：grid 70 15
m m
gen 0,0 0,900 2100,900 2100,0
prop s=2.6e8 b=3.3e8 d=2657 fric=30 coh=1e6 region 4,4
;-----切割地表，第一个点是x,y最小点，其它点顺时针排列-----

set grav=9.8

gen line 34.38,0 153.58,149.61 不知道怎么上传照片…… 切割地表用tab比较好 我也试过用线 线与线之间不连续 用tab名字则可以解决 如：
tab 1 48,90,58,67.37,93.28,49.87,112.7,45,125,45
gen tab 1
tab 2 47.23,90,57.51,67.48,93.03,49.21,112.67,44.3,125,44.3,125.99,45
gen tab 2
就可以生产两条连续折线
