《河海大学学报》１９９８年第５期刊载了王勇等撰写的“有限元计算深开挖中挖方等效荷载的分析”一文［１］，文中介绍了计算开挖面上释放荷载的两种方法．从基本原理看，开挖问题即是将开挖面上的应力完全解除，使其成为应力自由面，就此而言，两种方法的本质是一致的，但计 In the 5th issue of the Journal of Hohai University, 1998, the article “An Analysis of the Finite Element Computation of the Excavation Equivalent Load in Deep Excavation in Finite Element Calculations” was written by Wang Yong et al. [1]. Two calculations of the release load on the excavation surface are presented. This method. From the basic principle, the excavation problem is to completely relieve the stress on the excavation surface, making it a stress free surface. In this regard, the essence of the two methods is the same, but
