地下工程基础埋深对桩基础水平承载力有着重要影响,特别是当水平承载力起控制作用时,应确保基础具有足够的埋置深度。介绍了轨道交通车辆段停车场带上盖建筑开发项目桩基础水平承载力的设计方法;对基桩水平承载力的影响因素进行参数化分析,得出桩顶约束情况是最主要的影响因素;分析了高承台桩基与低承台桩基在水平荷载下整体桩基础承载力、基桩内力与变形的状况。
The basic depth of underground works has an important influence on the horizontal bearing capacity of pile foundation. Especially when the horizontal bearing capacity plays a controlling role, it is necessary to ensure that the foundation has sufficient depth of embedment. The design method of the horizontal bearing capacity of the pile foundation in the car park with a rail transit vehicle parking lot is introduced. By parametric analysis of the factors affecting the horizontal bearing capacity of the pile, it is concluded that the restraint of the pile top is the most important factor. The bearing capacity of pile foundations and the internal forces and deformations of pile foundation under the horizontal load are analyzed.
