Abstract
Taking a foundation pit project in Zhangzhou High-tech Zone as an example,this paper analyzes the influence of SMW pile+inter-nal support on the surface settlement and horizontal displacement of deep foundation pit excavation in soft soil area.The results show that the surface settlement of SMW pile+internal support at different monitoring points is the largest in June 2023,and the maximum settlement is 20、21、21、22、22 mm,respectively.Compared with May 2023,the land surface settlement increased by 11.11%、31.25%、10.52%、10.0%and 15.78%,respectively.The horizontal displacement of cement mixing pile supporting foundation pit is increased by 7.91%compared with SMW pile+inner support.The variation rules of numerical simulation and field test are consistent,and the difference between the two values is small.关键词
