摘要
华南地区土体多为黏土,土体具有含水量多、黏性大等特性。因此,在基坑施工开挖过程中,应充分考虑结构的强度、刚度和稳定性,确保基坑开挖变形处于安全范围内。论文基于华南地区典型地质,以某地铁车站基坑工程为研究实例,结合现场监测和数值模拟的方法,研究得出了围护桩刚度对基坑变形的影响规律。
The soil in South China is mostly clay,which has characteristics such as high water content and high viscosity.Therefore,during the excavation process of foundation pit construction,the strength,stiffness and stability of the structure should be fully considered to ensure that the deformation of the foundation pit excavation is within a safe range.Based on the typical geological conditions of South China,this paper takes a subway station foundation pit project as a case study and combines on-site monitoring and numerical simulation methods to investigate the influence of the stiffness of retaining piles on foundation pit deformation.
