单边加载下的深基坑水平位移分析

为分析和预判桩锚支护下的深基坑在单边加载状态下的顶部水平位移情况,采用有限差分法对基坑三维受力和变形状态进行模拟。结合某高层住宅施工过程中的深基坑监测项目进行实例验证,将模拟分析结果与实际监测成果进行对比。通过对比证明,在参数设置准确的情况下,有限差分模拟计算能较好地预测基坑边变形趋势,为安全监测项目方案的制定、指导施工荷载安放提供有力参考。

Horizontal Displacement Analysis of Deep Foundation Pit Under Unilateral Loading

In order to analyze and predict the top horizontal displacement of deep foundation pit under unilateral loading,the finite difference method was used to simulate the three-dimensional stress and deformation of foundation pit.Combined with the monitoring project of deep foundation pit in the construction process of a high-rise residential building,the simulation analysis results are compared with the actual monitoring results.Through the comparison,it is proved that the finite difference simulation calculation can better predict the deformation trend of foundation pit edge under the condition of accurate parameter setting,which provides a strong reference for the formulation of safety monitoring project scheme and the guidance of construction load placement.
