深基坑工程事故原因探析

Analysis on Causes of Deep Foundation Pit Engineering Accidents

深基坑工程是一个高风险、高难度,涉及多个学科和多种复杂因素相互影响的系统工程。由于在勘察、设计、施工、监测等环节的处理不当,近几年深基坑工程事故发生较多,有些还相当严重。通过论述深基坑工程特点,对深基坑事故发生的原因进行了全面的分析和探讨,提出了深基坑工程中应注意的问题,即重视深基坑工程勘察工作,优化深基坑工程设计,加强施工组织设计,实行施工过程质量控制和流程管理,注意信息化施工。可供从事深基坑工程的管理人员和工程技术人员借鉴。

Deep foundation pit project is a systemtic engineering of high risk, high difficulty, covering multi-discipline and interaction of muhi-factor. Due to unproper disposal on investigation, design, construction and monitoring, deep foundation pit engineering accidents have occurred more and more in recent years, and some are quite serious. The characteristics of deep foundation pit engineering is discussed to analyse the causes of accidents thoroughty, and proposes the question which should be adverted in the deep foundation pit engineering. The questions are showed as follows： valuing engineering investigation of deep foundation pit engineering, optimizing design of deep foundation pit engineering, strengthening construction organization design, implementing quality control in construction process, adverting information construction. The conclusions obtained may serve as reference for the administrators and technicians.
