某土钉墙工程现场实测研究

目前土钉支护的应用越来越广泛、应用的基坑越来越深,新的土钉支护形式也不断涌现,阶式土钉墙也是一种近几年出现的新的土钉支护形式。本文通过一个实际工程,对土钉支护结构水平位移和土钉内力进行实测,并将普通土钉墙与阶式土钉墙进行对比,工程实践表明:阶式土钉墙可以有效地减小土钉内力和土钉墙变形、提高整体稳定安全度。

Research on the Soil-Nail Wall by Field Tests

Soil-nail walls are used widely,and also used for deeper foundation pits.There are more and more new types of soil-nail walls;for example,the stepped soil-nail wall is a kind of new soil-nail wall.This paper introduces an instance of soil-nail wall engineering with both the common soil-nail wall and the stepped soil-nail wall,both the horizontal displacement and the nail force are tested in situ.The field tests indicate: either the horizontal displacement or the nail force of the stepped soil-nail wall are ...
