摘要
传统基坑支护一般选用钢筋混凝土支撑或钢支撑,虽然技术性和安全性能够得到较好地保证,但也存在安拆费时费工、经济性不强、对环境不友好的弊端。近年来,出现了一种自稳式基坑支护技术,相较于传统基坑支护施工,自稳式基坑支护的主要特点是能够实现基坑直立开挖,不仅改善了工作环境,提高了挖土效率,而且通过钢构件的回收和重复利用,有效降低了工程造价,显著缩短了工期。本文以某地下车库基坑开挖为背景,对自稳式基坑支护体系的施工细节进行介绍,分析了基坑变形控制效果,并与传统支护形式在工期、经济效益、环境效益等方面进行比较,以期为同类基坑施工提供一种新型、高效、经济的支护技术参考。
Traditional foundation pit support generally uses reinforced concrete or steel support.While these methods provide reliable technical performance and safety,they also have notable drawbacks,such as time-consuming and laborintensive installation and dismantling,limited economic efficiency,and negative environmental impacts.In recent years,a self-stabilizing foundation pit support technology has developed.Compared to traditional construction methods,the main characteristic of self-stabilizing foundation pit support is its ability to achieve vertical excavation,which not only improves the working environment and excavation efficiency but also significantly reduces project costs through the recycling and reuse of steel components and substantially shortens the construction period.Taking the construction of an underground parking garage foundation pit as a background,this article introduces the construction details of the selfstabilizing foundation pit support system and compares it with traditional support forms in terms of construction period,economic benefits,and environmental impacts.The study demonstrates the system’s significant advantages,providing a highly efficient,cost-effective,and environmental friendly support solution,aiming to provide a valuable technical reference for similar foundation pit construction projects.
