深基坑喷锚支护与工程灾害防治

The Anchor-Gunited Supporting Structures in Deep Foundation Pits and Treatment of Disasters in Engineering

阐述了深基坑锚喷支护和周边建（构）筑物的相互作用，分析了常见的深基坑喷锚支护工程灾害原因，结合３个典型的工程实例。

This paper describes mechanism and characteristics of anchor-gunited supporting structures in deep foundation pits,and the interactions between the surrounding structures and the supporting structures. The reasons of disasters in the anchor-gunited supporting engineering are analysed. The key of the problem is the deformation control of the deep foundation pits. Methods of treatment of disasters are also put forward based on some practical examples in engineering.
