研究了内支撑体系、支护结构与土三者共同作用的空间有限元计算法 ,较好地考虑了土与支护结构的共同作用及支护体系本身的空间效应 ;满足支护结构和支撑结构的位移协调 ;不必单独计算支撑刚度 ;对于封闭支护体系 ,不必确定边界条件 介绍了基坑支护 (JKZH)CAD系统的研究开发过程
The finite element method for calculating the interaction between the inner support system, the support structure and the soil is studied. The combined effect of the soil and the support structure and the space effect of the support system are considered. The support structure and the support The coordination of the displacement of the structure is not required; the stiffness of the support must not be calculated separately; it is not necessary to determine the boundary conditions for the closed support system. The research and development process of the JKZH CAD system is introduced
