摘要
本文针对深基坑开挖两种以上支护方式如何既经济、又能快速高效施工进行研究。以中国铁建淮北青秀城项目为例,结合现场地质及邻近建筑物干扰情况,对原支护设计方案进行优化研究,提出利用一种新型挡护结构——定型边坡挡墙+土钉墙两种支护方式相结合方案,弥补了单纯土钉墙支护强度不足的缺陷。本文对新型支护结构构造及支护原理进行详细阐述,并结合现场监测结果对支护效果进行评价。
This paper is aimed at the study of how to excavate the deep foundation pit with more than two supporting methods economically and efficiently. Taking the Qingxiucheng Project of CRCC in Huaibei as an example, combined with the on-site geology and the interference of adjacent buildings, the original supporting design scheme is optimized, and the scheme of a new supporting structure, namely, the combination of two supporting methods of slope retaining wall and soil nailing wall, is put forward, which makes up for the defect of insufficient supporting strength of the simple soil retaining wall. In this paper, the construction and supporting principle of the new type of supporting structure are described in detail, and the supporting effect is evaluated based on the on-site monitoring results.
