土钉支护结构的设计及应用

土钉支护是用于土体开挖和深基坑施工时保证边坡稳定的一种新技术,该技术具有材料用量少、施工速度快、安全可靠、经济等特点。本文首先结合土钉墙的概念介绍了土钉与锚杆的区别,然后阐释了土钉的构造、设计原则及稳定性分析的方法,最后分析了西安建筑科技大学华清学院的土钉支护实例,对其中两个剖面的设计过程进行了详细说明,并进行了稳定性验算,由此指出了土钉墙广阔的应用前景。

Design and Application of Soil -nail Braced Structure

Soil nailing is a new technology that is used for soil excavation and deep foundation construction to ensure the slope stability, which is used with less material, high speed of construction, safe and reliable, inexpensive, and so on. First, introduce the difference between nall and anchor bolt with the concept of soil nailing wall, then explain the structure, design principles and methods of stability analysis of soil nails, finally, analysis the soil nailing example of Xi＇an University of Architecture and Technology Huaqing College, the design process of two sections is described in detail, and the stability checking is carried out, thus point to the broad application prospects of soil nailing wall.
