系统分析了某深基坑坍塌事故的原因，得出了如下认识：①岩质基坑侧壁受光滑结构面影响，设计应按平面滑动模式验算整体稳定性；②根据不同断面地质条件与受力特点划分不同支护单元，合理设计构造措施；③采取动态设计法，结合开挖情况，分析地层参数、边界条件与设计前提是否吻合并及时调整设计；④重视施工监测结果，并采取应对措施等。

In this paper,a comprehensive analysis of the causes of a deep building foundation excavation collapse were carried out ,draws the following he following conclusions,it could provide a reference for similar projects.:(1)the stability of rock pits was controlled by structural plane,the stability design should be calculated based on sliding mode plane.( 2 ) The different retaining and protection structure should be designed focus on the geological conditions and stress condition.(3) Information based design should be attached pay more attention on the situation of excavation.the design parameters are consistent with the analysis of the stratum condition and boundary condition.designs must be ad-justed in time on it.(4) More attention should be paid on the results of construction monitoring,the corresponding contin-gency measures must be taken while abnormal deformation happens.
