护坡桩截面刚度对桩锚支护体系的影响研究
摘要:依托北京某基坑工程,针对桩锚支护结构,采用理论分析、计算对比的方法,研究了护坡桩截面刚度对桩锚支护结构的力学性状与形变的影响,给出了优化护坡桩截面刚度的建议。通过数值模拟计算以及实际工程的监测验证了截面刚度优化后支护体系的稳定性。
Abstract:Based on the construction of a project in Beijing,behavior mechanism and deformation properties of pile-anchor structure are obtained in this article by using theoretical method and orthogonal test analysis.Some suggestions that how to optimize the pile section on foundation pit supporting design are given here.A FLAC3D model is built nextly,the above conditions are carefully verified again.At last,according to the monitoring data,it takes the conclusion that the pile-anchor structure optimized section can assure the pit safety with meeting requirement of national standards.
