十分感谢章青先生对笔者原文“有限元计算深开挖中挖方等效荷载的分析”的讨论，讨论对提高文章的质量，沟通读者与笔者的联系无疑是有意义的．下面对讨论中涉及的问题，作粗浅的解答．１ 挖方等效荷载的计算原理开挖问题的基本原理是将开挖面上的应力完全解除，从而使开挖面
I am very grateful to Mr. Zhang Qing for his discussion of the original “analysis of the equivalent load of excavation in deep excavation by finite element calculation”. It is of great significance to discuss improving the quality of the article and communicating the reader’s and the author’s contact. Here are some rough answers to the questions involved in the discussion. 1 Principle of calculating the effective load of the excavation The basic principle of the excavation problem is to completely relieve the stress on the excavation surface so that the excavation surface
