摘要: 基坑倾斜桩支护技术具备控制变形效果佳,施工速度快,工程造价低等优点。然而,目前缺乏对基坑倾斜桩支护技术在控制变形方面的系统研究和各种组合支护形式的效果验证。采用有限元软件Plaxis3D,对比了多种倾斜桩组合支护结构在控制桩身变形和坑外沉降方面的特性。

Abstract: The application of inclined piles can efficiently limit the deformation of retaining structures, save the cost and reduce the duration of the construction. However, there are few researches on the theories and technologies about the deformation and various forms of inclined piles. A series of inclined pile-retained excavation models simulated by FEM software Plaxis3D are employed to estimate the characteristics of pile deflection and ground settlement of several different inclined pile-retained excavations.
