excavation separatrix

By the method and procedure in this paper, the stress and strain of supporting structure are studied under the condition of different heaped load,excavation depth, excavation separatrix location and soil mass condition.
利用本文的计算方法及程序,分别计算分析了外加荷载不同、开挖深度不同、挖深分界不同、两侧土质不同等四种情况下支护结构的内力和变形。
