摘　　要：基坑的变形和受力机制复杂,如果支护设计不当或施工控制不合理,可能出现基坑坍塌、失稳等问题,从而造成一定的人员伤亡和经济损失。为了解决这一问题,文章以某住宅建筑的地下室基坑为例,分析了基坑设计原则,对支护方案进行比选,利用数值软件优化了支护桩参数(桩长、桩间距),并进行了基坑稳定性验算。随后,分析了该基坑施工期间出现的问题,提出了相应的解决措施,研究成果可为类似基坑工程建设提供参考。The deformation and stress mechanism of foundation pit is complex.If the support design is improper or the construction control is unreasonable,problems such as foundation pit collapse and instability may occur,resulting in certain casualties and economic losses.In order to solve this problem,this paper takes the basement foundation pit of a residential building as an example,analyzes the design principles of the foundation pit,compares and selects support schemes,optimizes the parameters of the support piles(pile length and pile spacing)by numerical software,and carries out checking calculation of the foundation pit stability.Then,the problems during the construction of the foundation pit are analyzed,and the corresponding solutions are put forward.The research results can provide reference for similar foundation pit engineering construction.
