摘要
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)
The finite element method of co operation of the internal bracing system, shoring structure and soil in 3 dimensions was studied It is thought over that the common effect of soil and shoring structure and the domino effect of shoring system. Displacement of shoring structure and bracing structure are well coordinated. Stiffness of brace needn't be calculated. To the close shoring systems, it needn't define conditions of the boundary. The work of a Foundation Pit Bracing System CAD (JKZH CAD) is introduced.
