【摘要】 基坑工程在现代城市建设中应用广泛,而基坑工程的复杂性、不可预见性又要求必须对基坑支护结构稳定性进行实时监测。本文阐述了基坑监测中基本原则,并结合西宁市城东区共和路东侧一深基坑变形监测项目,通过任意设站极坐标法对支护结构顶部水平位移监测点进行观测,及时反应支护结构在突发情况下的变形情况,准确的分析基坑变形原因并提供处理依据,保证了基坑及周围建筑的安全。更多还原

【Abstract】 Foundation pit engineering is widely used in the construction of modern city,but it is complex and unpredictable. So we must carry out the real-time monitoring on the stability of foundation pit supporting structure. This paper describes the basic principles of the foundation excavation,combined with a deep foundation pit deformation monitoring project on the east side of the Gonghe Road,the east area of Xining City,By arbitrary station polar coordinate method,the horizontal displacement of retaining structure monitoring points was observed so as to know the deformation of supporting structure timely response in an emergency. Analysis of foundation pit deformation can provide accurate basis for handling and to ensure the safety of foundation pit and the surrounding buildings.更多还原
