基于监测大数据的地表沉降控制值研究

Analysis of Surface Subsidence Control Value Based on Monitoring Big Data

城市轨道交通工程建设多处于复杂的城市环境中,其安全风险的控制至关重要。监测项目控制值的大小不仅直接影响到工程自身和周边环境的安全,对设计方案、施工方法的制定及工期造价也会产生很大影响,因此,合理地确定监测项目控制值是一项十分重要的工作。为了进一步精确地表沉降控制值,通过总结分析目前监测项目控制值相关研究成果,基于大量的工程监测数据资料,对城市轨道交通工程地表沉降控制指标进行了系统的统计分析研究,最终给出了不同地层、不同工法的区间及车站地表沉降控制值的建议值。

Urban rail transit engineering construction is mostly in the complex urban environment,and its safety risk control is very important.The size of monitoring project control value not only directly affects the safety of the project itself and the surrounding environment,but also has a great impact on the formulation of design scheme,construction method and construction period cost.Therefore,reasonable determination of the control value of the monitoring project is a very important job.In order to further accurately control the surface settlement,through summarizing and analyzing the relevant research results of the current monitoring project control value,based on a large number of engineering monitoring data,the paper makes a systematic statistical analysis and research on the ground settlement control index of urban rail transit engineering,and finally gives the recommended values of surface settlement control value of different strata,different construction methods and stations.
