桩基挡墙,挡墙的挡土部分为悬臂式挡墙,基础部分采用钢筋混凝土钻孔灌注桩或打入桩等。以桩基作为挡墙结构的基础,解决了一般悬臂式挡墙必须依靠增大基础尺寸来提供抗倾覆滑移反力和减小地基承载力的问题,进而能够减小挖方段的开挖量,文中通过对桩基挡土墙案例的分析,说明其计算过程和适用性。 The retaining wall of pile foundation and retaining wall is a cantilever retaining wall, and the foundation part is reinforced concrete bored pile or driven pile. Taking the pile foundation as the foundation of the retaining wall structure, the problem that the general cantilever retaining wall must rely on increasing the foundation size to provide the anti-overturning slip reaction force and reduce the bearing capacity of foundation is solved, and the excavation volume of the excavation section can be reduced In this paper, the pile foundation retaining wall analysis of the case illustrates its calculation process and applicability.
