随着我国建筑技术的不断发展,高层建筑在地下空间的利用方面越来越多,因此工程共边坡供与深基坑工程规模和技术难度也都越来越大。本文针对复合土钉应用现状进行简单介绍,以某建筑深基坑支护设计为例,对应用水泥搅拌桩复合土钉支护方案在深基坑支护中的效果进行研究,得到该支护方案在控制形变与周边环境保护方面的结论。
With the continuous development of building technology in our country, the use of high-rise buildings in underground space is more and more. Therefore, the project scale and technical difficulty of supply and deep foundation pits for engineering are also increasing. In this paper, the application status of composite soil nailing is briefly introduced. Taking the design of deep foundation pit support of a building as an example, the effect of using composite soil nailing support scheme of cement mixing pile in deep foundation pit support is studied. Program in the control of deformation and the surrounding environmental protection conclusions.
