黏土地层中桩锚支护结构土压力分布研究
摘要:桩锚支护结构以其技术要求低、适用性广的特点备受设计和施工单位青睐。但当前岩土工程依然存在实践超前理论的现象,技术的不断进步势必要对基坑工程提出更高的设计要求。利用FLAC3D对顺义区某深基坑工程进行仿真分析,模拟出桩侧土压力分布曲线。与经典土压力理论进行对比,桩身位移、锚杆拉力模拟值与实测值更加接近,认为模拟土压力分布曲线更加符合工程实际。提出的黏土地层桩锚支护结构土压力分布形式,对于优化结构设计,降低施工成本具有重要意义。
Abstract:The pile-anchor supporting structure with its low technical requirements and wide applicability has been highly received by the design and construction units.But the current practice of geotechnical engineering remained ahead of theory,the progress of technology must put forward higher design requirements on foundation pit.Analysis of a deep foundation pit in Shunyi district by FLAC3D,simulate the curve of soil pressure distribution.Compared with the classical soil pressure theory,the displacement of the pile,the tension of the anchor is close to the measured value.The simulate curve of soil pressure distribution accord with engineering practice more.In this paper,the research of the soil pressure distribution in silty clay is very important for optimizing the structure design and reducing the construction cost.
