Abstract
Based on a certain deep foundation pit engineering project,a finite element model of the foundation pit was established,and com-bined with on-site monitoring data,the deformation of the support structure after excavation was analyzed.The results show that the deforma-tion of the double row pile support structure in the project is close to that of a cantilever structure.Compared with the measured results,the maximum horizontal displacement of the pile top obtained from numerical simulation is smaller;The double row pile with anchor cable support structure has a relatively small impact on the maximum horizontal displacement of the pile top due to the angle of anchor cable incidence;Com-pared with the situation where the distance between the front and rear piles of double row piles is 5 meters,when the distance between the front and rear piles is 3.5 meters,the maximum horizontal displacement of the pile top is reduced by 68.5%.关键词
