土体变形破坏与基坑失稳

The relation of soil deformation and failure with foundation pit destabilitization

本文通过工程实例，分析了基坑土体变形破坏与基坑失稳的相互关系，进一步分析了土体变形破坏在分布及大小上的不均一性，指出了突破点形成、转移及控制的概念。最后针对桩后裂缝的形成，简要分析了突破点转移在工程中的应用。

This paper analyses the relation of soil deformation and failure with foundalion pit destabilibization through engineering cases. It further analyses the nonuniformity in distribution and degree of soil de formation and failure. The concept of the formation, transference and controlling of the break Chrough point is put forward. The application of the transferenel of the breakthrough point in accordance with the crack formation after pole is briefly analyzed.
