摘要

摘要: 根据文献中对主要位于深圳和广州地区10个土钉墙及复合土钉墙工程的侧移记录，对土钉墙及复合土钉墙侧移经验计算方法进行了改进，验证并建议了土钉变形模量、土钉影响直径和变形零点系数的取值范围。结果表明：虽然计算所得侧移曲线在土层分层处有突变，但与实测曲线基本符合，可以满足工程设计要求。

Abstract: Based on the literatures of horizontal displacement records for soil-nailing and composite soil-nailing walls about 10 projects mainly located in Shenzhen and Guangzhou, the improvement of the empirical methods for horizontal displacement of soil-nailing and composite soil-nailing walls is performed. The numerical ranges of the deformation modulus of soil nails, the influence diameter of soil nails and the coefficient of null deformation are suggested. The calculated results show that the proposed method is credible in practice according to the comparison between the computational data and the test data, although the computational curves are discontinuous on interfaces of the layered soils.
