High bearing platform anchoring type pile foundation joist retaining wall structure and construction method
The invention discloses a high bearing platform anchoring type pile foundation joist retaining wall structure and a construction method, the high bearing platform anchoring type pile foundation joist retaining wall structure comprises a pile foundation, a joist, a retaining wall and an anchoring type structure, and the retaining wall bears the filling load above the wall bottom; the joists provide effective bearing force for the retaining wall, are connected with the lower pile foundation and serve as bearing platforms to coordinate stress of the pile foundation. The pile foundations bear horizontal and vertical loads and slope thrust or gliding force transmitted by the upper retaining wall through the joists; by means of the anchoring structure acting on the joist, part of side slope thrust or gliding force is balanced through the prestress effect, meanwhile, the deformation problem of the pile top is effectively controlled through the deformation coordination effect, and compared with a traditional anchor cable anchoring structure in filling engineering, the anchoring structure has the advantages of being good in stress, high in safety, low in engineering cost, convenient to construct and the like.
本发明公开一种高承台锚拉式桩基托梁挡土墙结构及施工方法，包括桩基、托梁、挡墙和锚拉式结构四部分，挡墙承受墙底以上的填土荷载；托梁为挡墙提供了有效的承载力，同时连接下部桩基，兼做承台，协调桩基受力；桩基承受由上部挡墙通过托梁传递的水平、竖向荷载与边坡推力或下滑力；作用于托梁上的锚拉式结构，则通过预应力作用平衡了部分边坡推力或下滑力，同时通过变形协调作用有效的控制桩顶变形问题，相较于填方工程中传统的锚索锚拉式结构，本发明具有受力好、安全性高、工程造价低、施工便利等方面的优势。
