摘要
近年不少建筑物为追求临江的建筑景观或受到场地限制,地下室施工必须在临近海(江)边的地方进行,这就给基坑支护设计及施工提出了很高的要求。文中结合广州珠江边某工程实例,详细描述了支护选型对比过程,列举了项目遇到的设计难点及解决方案,并结合基坑监测结果对基坑变形、珠江周边堤岸及基坑周边建筑物沉降变形进行了分析,结果表明采用地下连续墙支护方案止水效果良好,支护结构及基坑开挖影响范围内沉降及变形均满足规范要求,可为基坑设计及施工提供依据。
Because of landscape near the river or limted space in recent years,basement mt, st be builded near the sea （river）,that brings lots of challenges to dip pit design and construction. According to a project in Guangzhou near the Pearl River,shoring system selection pro- cess is described,difficulties in design and solution are given. Combined with monitoring results,deformation of foundation pit,embankment, settlement deformation of surrounding buildings are analyzed. The results prove that underground continuous wall have good effect on wa- ter-stop. Supporting structure and influence of excavation of foundation pit all meet standard requirements.lt may provide certain basis to de- sign and construction of the deep pit.
