【摘要】 结合惠州龙门第二自来水厂基坑特点及支护形式和周边环境,有针对性地制定了基坑监测方案。通过使用测斜仪、全站仪、水准仪和水位计等对基坑的深层水平位移、边坡坡顶水平位移、周边需保护建筑的沉降、周边土体沉降和周边的地下水位等项目进行了跟踪监测。结果表明:各项监测项目之间存在一定的关联性,对各监测项目的连续监测数据进行综合分析可知,各监测项目的结果具有良好的一致性。为了确保现有水厂的正常运营,及时反映基坑自身及周边环境的实际状态,有必要对基坑工程进行动态监测。更多还原

【Abstract】 According to the characteristics of the supporting structures and surrounding environment of the foundation pit of the second water treatment plant in Longmen,Huizhou,a targeted monitoring scheme for the foundation pit was established. The horizontal displacement of depth layers and the slope top,the settlement of surrounding buildings and soil,as well as the underground water level were monitored by using the inclinometer,total station,level and water level indicator. The monitoring results indicate that the monitoring items are related to some extent,and the results of which are in consistency based on the comprehensive analysis of the continuous monitoring data It’s necessary to monitor the foundation pit dynamically,in order to ensure the regular operation of the existing water plant and reflect the virtual condition of the foundation itself and the surrounding environment in time.更多还原
