摘要
介绍了沉降监测的基本理论和方法,以钱营孜煤矿为例,建立了沉降监测系统,采用水准测量对监测系统进行定期监测,数据处理和分析。建立了能反映监测动态变化的灰色GM(1,1)等维新息模型,得到:地表沉降与水位变化呈现显著的相关关系,井架基础最大沉降量138mm,最大沉降差为3mm,并对监测点下一期的沉降值进行了预测。研究成果对于工业广场沉降治理具有指导意义。
This paper introduces the basic theory and method on subsidence monitoring. Taking the Qian yingzi coal mine for example, establish a settlement monitoring system. Using the geomantie leveling method to regularly monitor, data processing and analysis for the monitoring system. The new-information model GM（1,1） which could reflect the engineering dynamic change was set up. The ultimateness illustrated： a significant relationship between Surface subsidence and water level changes have been presented, the largest settlement of Derrick foundation is 138ram,the settlement of Maximum differential is 3mm, and then the next sedimentation value for the monitoring point was forecasted. The results of the research have a guiding significance for the control of industrial square settlement.
