喷锚支护结构设计及其在成都地区深基坑护壁工程中的应用

Design for AnchorShotcrete Support Structure and Its Applicaion to Protecting Wall Works of Deep Foundation Pit in Chengdu Area

近年来，喷锚支护技术在深基坑护壁工程中得到比较广泛的应用，本文简述了喷锚支护基本原理和施工工艺，提出了有别于洞室喷锚支护的深基坑支护强度、稳定计算方法和变形控制要求及构造措施，并介绍了在成都地区应用喷锚支护技术进行深基坑护壁的若干工程实例。

In recent years, anchorshotcrete support technique has been widely used to protect wall works of deep foundation pit.This paper summaries its basic principle and construction technology and demonstrates the support strength,stabilitycalculating method, deformationcontrol requirements and construction measures of the deep foundation pit, which differs from those of underground openings. A number of studied cases are also presented of various protecting wall works conducted with anchorshotcrete support technique in Chengdu area.
