【摘 要】深基坑支护工程虽属临时性工程，但其施工方案的可靠性及施工质量将直接影响地下室主体施工的结构和作业工人人生安全，且其施工的技术复杂性，有的却远甚于永久性的基础结构或上部结构，稍有不慎，不仅将危及基坑本身安全，还会殃及临近的构筑物和各种地下设施，造成巨大损失。本文分析了当前深基坑支护存在的安全问题，提出了深基坑支护设计施工中的注意事项和预防措施。

【Abstract】Deep Foundation Pit Engineering, although the temporary works, but the reliability and quality of construction of its construction program will directly affect the life safety of the basement of the main construction and operating workers, and the construction of technical complexity, but some even more thanpermanent infrastructure or superstructure, the slightest mistake, will not only endanger the pit itself is safe, will bring disaster to the adjacent structures and a variety of underground facilities, resulting in huge losses. This paper analyzes the security issues in Deep Foundation Pit, precautions and preventive measures in the design and construction of deep foundation pit support.

1. 前言
近几年来，高层建筑的迅速兴起，促进了深基坑支护技术的发展。各地在深基坑开挖和支护技术方面积累了丰富的设计和施工经验，新技术、新结构、新工艺不断涌现。但是，现在的城市建筑间距很小，有的基坑边缘距已有建筑仅十几米、甚至几米，给基础工程施工带来很大的难度，给周围环境带来极大威胁，也相应地增加了施工工期和施工费用。另外，原来的深基坑支护结构的设计理论、设计原则、运算公式、施工工艺等，已不符合深基坑开挖与支护结构的实际情况，导致一些基坑工程出现事故，造成巨大的损失。因此，深基坑支护的安全问题工程技术人员应予以高度重视。
