大浦第二抽水站工程地质为深厚海淤土,距离已建大浦第一抽水站外边线仅相距35.25 m,施工时为确保相邻建筑物的工程安全,经综合分析建筑场地的工程地质特征、基坑开挖深度、周边荷载、基坑位移对主体结构及周围环境的影响等因素,采用水泥土深层搅拌桩加固、在基坑东侧边沿布置一排钢筋混凝土钻孔灌注桩的组合支护模式,同时加强对组合支护桩及周围建筑物的安全监测等措施,解决了该站基坑开挖、施工降排水对周围建筑物安全的不利影响。

The engineering geology of Dapu second pumping station is deep sea silt,35.25 m apart from Dapu first pumping station. In order to ensure engineering safety of neighboring buildings,engineering geological characteristics,excavation depth,surrounding load,displacement of foundation pit of the construction site on the main structure and the surrounding environment are comprehensive analyzed. Combined support mode of cement mixing pile and concrete bored pile reinforcement is used. Measures of safety monitoring for combined support pile and surrounding buildings are taken. The adverse effects coursed by construction of excavation and drainage on safety of surrounding buildings are solved.
