安徽省芜湖县湾沚地区近年来兴建多处一层地下室,其基坑围护多采用土钉墙形式。由于缺乏地区设计经验,加之该地区地处江南降水量丰沛地带,一到雨季,土钉墙失稳破坏现象时有发生。该文结合某一工程实例,探讨这一地区较为合理、经济的土钉墙围护形式,以及基坑开挖和围护施工过程中应注意的问题。 In Wuhu County, Anhui Province, there are many basements constructed in Wanli district of Wuhu County in recent years, and the foundation pit protection is mostly in the form of soil nailing wall. Due to the lack of regional design experience, combined with the area is located in the abundant precipitation in the southern region, once the rainy season, soil nail wall instability has occurred from time to time. In this paper, a project example is discussed to discuss the reasonable and economical form of soil nailing support in the area and the problems to be noticed in the excavation and enclosure construction of foundation pit.
