建筑工程基坑支护设计研究

Research on the Design of Foundation Pit Support in Construction Engineering

建筑基坑受力和变形复杂,支护设计难度大。为了保证基坑安全,应加强支护设计。分析了常用基坑支护方法的使用条件和设计要求,以某建筑工程基坑为研究对象,对基坑支护桩、水平支撑、土钉墙等开展了详细设计。随后,在基坑周边道路设置监测点,监测了路面沉降变化,发现基坑支护效果良好,研究成果可为类似基坑工程支护设计提供借鉴。

The stress and deformation of building foundation pits are complex,and the design of support is difficult.In order to ensure the safety of the foundation pit,the support design should be strengthened.Analyzed the usage conditions and design requirements of commonly used foundation pit support methods,and conducted detailed design on foundation pit retaining piles,horizontal supports,soil nail walls,etc.,taking a certain construction project foundation pit as the research object.Subsequently,monitoring points were set up on the roads around the foundation pit to monitor changes in road surface settlement.It was found that the support effect of the foundation pit was good,and the research results can provide reference for similar foundation pit engineering support design.
