断裂力学是近年来新兴的一门综合学科 ,本文将断裂力学的基本原理与土的强度理论相结合 ,采用适用于土体的抗裂强度理论 ,建立开裂后土体的本构关系 ,分析土体开裂对基坑支护结构的影响。开发了弹塑性有限元程序。并将程序的计算结果与模型实验的结果进行了对比
Fracture mechanics is a new comprehensive discipline in recent years. In this paper, the basic theory of fracture mechanics and soil strength theory are combined. Using the theory of fracture strength suitable for soil, the constitutive relationship of soil after cracking is established. Influence of Body Cracking on Foundation Pit Support Structure. Elastic-plastic finite element program was developed. The results of the program are compared with those of the model experiment
