【摘要】：高铁沿线施工期间引起地面沉降的因素错综复杂、相互影响,本文提出通过对沉降区域地下水位、孔隙水压力等进行分层观测,根据分层观测得到地下水位变化、孔隙水压力变化等数据,并采用回归分析法构建了沉降区域地面沉降与诸影响因子的关联模型,通过对郑徐客运专线开封段进行的地面沉降监测量与同时采用二等精密水准测量得到的监测点沉降量进行对比分析,结果表明本方法的有效性和可靠性。
[Abstract]:The factors that cause the ground subsidence along the high-speed railway line during construction are complicated and influence each other. This paper proposes that the groundwater level changes can be obtained by stratified observation of groundwater level and pore water pressure in the settlement area. Based on the data of pore water pressure variation and regression analysis, the correlation model between land subsidence and influencing factors in subsidence area is established. By comparing the ground subsidence monitoring quantity of Kaifeng section of Zhengxu passenger dedicated line with that of the monitoring point obtained by using the second class precision leveling at the same time, the results show that the method is effective and reliable.
