土钉支护对紧邻建筑物变形的数值模拟与施工监测对比分析

STUDY ON SETTLEMENT AND DEFORMATION OF THE ADJACENT BUILDING IN A DEEP FOUNDATION PIT UNDER SOIL-NAILED SUPPORTING BASED ON CONTRASTING THE RESULT BY NUMERICAL SIMULATION WITH ONE BY ON-THE-SPOT MONITORING

根据具体工程,将深基坑、土钉支护结构、紧邻建筑物放在一个系统研究。在对紧邻建筑物变形进行数值计算的同时也在施工过程中对紧邻建筑物变形从基底到顶部进行全面监测,然后对比分析二者结果,证明了支护方案的可行性,为深基坑工程的安全施工提供了一定的指导作用。

According to an instance of deep foundation excavation projects, deep foundation excavations, supporting structure and adjacent building are put into one system. The deformations of adjacent building are simulated and analyzed numerically. During the construction, the deformations of adjacent building are monitored particularly from bottom to top. Contrasting the simulation results with the results monitored, It is proved that the designed scheme of supporting for foundation pit is feasible, and gives a direction for the design and construction of deep foundation excavation engineering.
