土钉与桩锚联合支护结构的计算模式

The calculation model of the combined support struture of soil-nailing and pile-anchor

土钉与桩锚联合支护结构是由土钉支护与桩锚支护共同构成。在基坑边壁土压力及其它各种荷载作用下,土钉与桩锚作为一个整体共同抵抗荷载和变形。本文从分析土钉支护结构的受力特点、施工特点和破坏类型入手,研究分析了土钉与桩锚联合支护结构的协同工作机理,以及土钉与桩锚联合支护结构的设计计算内容与方法。

The combined support structure of soil-nailing and pile-anchor consists of the soil-nailing retaining and the pile-anchor retaining. With the effect of the foundation pit wall earth pressure and other kinds of loads, the soil-nailing and pile-anchor, as a whole,supports the loads and deformation. With the beginning of analyzing the pressure features; the construction features and failure types, the cooperation mechanism of the combined support struture of soil-nailing and pile-anchor is studied and researched, together with the contents and methods of designing and calculating.
