摘要
结合深圳某深基坑工程,采用数值模拟分析和现场监测的方法,对深基坑开挖过程中地下水位变化对周边沉降影响进行数值模拟分析和实时监测,分析了在已有支护方式的情况下深基坑开挖地下水位变化对工程周边沉降的影响。数值分析和实测结果表明:深基坑开过程中地下水位变化、基坑周边沉降以及地铁隧道的总位移均在控制范围内,周边建筑物均是安全的,并且该预测结果可用来指导施工。
Combined with a deep foundation excavation project in Shenzhen,the numerical simulation analysis method is used to simulate the influence of groundwater level change on the surrounding settlement of deep foundation excavation,and the variation of groundwater level in deep foundation excavation under the existing support mode is analyzed.The impact on the settlement around the project.The numerical analysis results show that the groundwater level change during the deep foundation excavation opening,the settlement around the foundation excavation and the total displacement of the subway tunnel are within the control range,and the surrounding buildings are safe,and the prediction results can be used to guide the construction.
