摘要
为了求解带有交叉施工缝的大体积混凝土结构的应力分析问题，导出了能够反映不同类型施工缝传力特征的物理方程式，提出了以空间接触面单元为基础的“变增量搜索法”迭代方案。所提出的分析方案能够考虑接缝面上不同方向的抗剪能力，考虑缝隙随接缝位置、高程和荷载施加而变化的情况以及不同接缝间的相互影响。文中提供的两个算例表明。
In order to analyze the stress of mass concrete structure with cross construction joints,this paper gives some physical equations which could reflect force transmission features of different construction joints,and puts forward the iteration alternative of variable increment searching method which is based on the space interface elemcnt.This analysis method considers different shear forces in different directions on the joint surface,the variation of joint with its position,elevation and load fluctuation,and the interaction of different joints.Two case studies in this paper show this method could effectively and correctly solve the stress analysis of mass concrete structure with cross construction joint.
