The nearer to the footofslope, the higher the value is. And it restores gradually to the primitive stress condition towards the inner part of the slope.
剪应力最大值出现在坡脚，其总趋势由内向外增多，愈近坡角愈高，向坡内逐渐恢复到原始应力状态。

Moreover, the Genetic Algorithms does not assume that the most dangerous sliding surface must pass footofslope, which is determined by the searching course at random.
此外，遗传算法没有边坡危险滑动面一定要通过坡脚的假定，而是随机的搜索确定的。

At the footof the slope there are cinder block houses, but as you climb the ridge, concrete gives way to wood and tarpaulin, then cardboard and twigs.
