地下工程风险管控第三方监测关键技术探讨

地下工程风险管控实施第三方监测,在对工程水文地质、施工中可能遇到的问题等风险源界定与辨识的基础上,结合数值模拟对监测点进行监测。介绍沉降监测点、桩顶水平位移监测点、桩体水平位移监测点、轴力计监测点等布设及监测方法;介绍监测数据分析方法一般步骤及流程及其如何剔除粗差,重点介绍数据拟合、数值模拟、等值线分析、曲线斜率等数据分析方法;结合工程水文地质、施工进度、现场巡视情况进行综合分析并给予安全评估建议。

Discussion on Key Monitoring Technologies Used by Third-Party in Management and Control of Underground Engineering Risks

The third-party as a monitoring side is monitoring the monitoring points with an assistance of numerical simulation based on the definition and identification of risk source of engineering hydrology geology and problems encountered in the construction.It introduces displacement of monitoring points and monitoring methods for the settlement of monitoring points,monitoring points for top of pile horizontal displacement,body of pile horizontal displacement,and the axial force meter monitoring points.The paper also introduces the general steps and processes for the methods of monitored data analysis and how they remove the rough and error data.The paper focuses on data fitting,numerical simulation,isoline analysis,the slope of the curve and other data analysis methods.By considering the engineering hydrogeology,construction progress,site visits to conduct a comprehensive analysis of safety assessment,it also gives recommendations.
