复合土钉工作机理与变形控制分析

Working Mechanism and Deformation Control of Composite Soil Nail Structure

在论述土钉的基本概念与工作机理的基础上,介绍了复合土钉的一般形式及其适用条件,着重分析了复合土钉的工作机理;同时,以土钉与水泥土桩墙组合式复合土钉为例,研究讨论了复合土钉变形的影响因素以及设计阶段和施工中的变形控制措施,可供研究与工程参考。

After discussion on concept and working mechanism about soil nail, the general forms and corresponding applications of composite soil nail are summarized, focusing on its working mechanism. Taking the form of composite soil nail and cement-reinforced-soil pile array as an example, the factors which affect the final deformation are discussed and the deformation control measures are suggested, which provide the reference for the research, design and construction.
