摘要
盐碱土具有孔隙结构大,压缩性高,强度低,工程性能差的特点。为研究盐碱土地区基坑开挖对基坑变形的影响,文章通过盐碱土高水位地区深基坑变形特征的现场试验,阐明了地面沉降、围护结构、支护轴力的变形规律。研究结果可为类似盐碱土地区深基坑的挖掘和变形预防措施提供参考,确保基坑的安全性和稳定性。
Saline alkali soil has the characteristics of large pore structure,high compressibility,low strength,and poor engineering performance.In order to study the influence of excavation of foundation pits in saline alkali soil areas on the deformation of foundation pits,this article clarifies the deformation laws of ground settlement,retaining structures,and support axial forces through field experiments on the deformation characteristics of deep foundation pits in high water level areas of saline alkali soil.The research results can provide reference for excavation and deformation prevention measures of deep foundation pits in similar saline alkali soil areas,ensuring the safety and stability of the foundation pits.
