摘　　要：深基坑开挖降水可引起周边环境的变化,尤其是引起周边地表管线及建筑物的沉降。通过合理、及时的进行基坑周边环境沉降监测,掌握周边环境变化规律、发展趋势,从而达到安全预警、反馈设计、指导施工的目的。介绍了基坑降水设计、周边环境监测设计并通过对观测资料的初步分析,指出:对深基坑降水作业的监测,应满足尽早、快速、及时、量化的要求,准确掌握周边环境的变化动态,采取切实可行的应急措施,以保证周边环境的安全。Dewatering of deep foundation pit can cause changes of the surrounding environment,especially the settlement of surface pipeline and surrounding buildings.Though reasonable and timely monitoring on the settlement,we manage to obtain variation laws and development trend of the surrounding environment for early safety-warming,feedback for design and guiding construction.The dewatering design for the deep foundation pit and monitoring on surrounding environment are introduced,and the observation data are analyzed preliminarily.It is pointed out that the monitoring on the dewatering operation of the deep foundation pit should be early,fast,timely and quantitative;the changes of the surrounding environment should be mastered to adopt feasible emergency measures for ensuring the safety of the surrounding environment.
