摘要

摘要: 以兰州市某深基坑为背景,针对其工程地质、水文条件进行深基坑支护及降水设计,采用井点降水及有组织引流排水措施,同时对支护结构水平、竖向位移,基坑周边建筑物沉降实时监测。监测结果表明：该降水方案条件下,支护结构位移及周边建筑物沉降量均得到良好的控制,为兰州市类似工程施工提供宝贵的经验。

Abstract: For a deep foundation pit in Lanzhou, its support and dewatering are designed according to the engineering geological and hydrological conditions. The measures of well-point dewatering and organized drainage are adopted, and real-time monitoring of horizontal and vertical displacements of supporting structures and settlement of buildings around the foundation pit is made. The monitoring results show that under the dewatering scheme the displacement of the supporting structures and settlement of surrounding buildings are well controlled. It may provide valuable experience for the construction of similar projects in Lanzhou.
