长短双排支护桩的简化算法及应用

摘要

在建筑基坑施工时，为确保施工安全，防止塌方事故发生，必须对开挖的建筑基坑采取支护措施。本文提出了长短双排支护桩的简化算法及有关实际案例分析，说明在特定条件下该方法是较安全可靠又经济实用的。%In the construction of foundation pit construction , to ensure the construction safety and to prevent the collapse accidents of build -ing foundation pit excavation , supporting measures must be taken .This paper presents a simplified analysis of the algorithm and the length of double row piles with different length on the actual case .It shows that under certain conditions the method is safety reliable and economi-cal and practical .
