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: In this paper, the factors that cause the land subsidence during the construction of high-speed railway are complicated and interactional. It is proposed that the ground water level and pore water pressure in the subsidence area are stratified observation, and the data of groundwater level change and pore water pressure change are obtained according to stratified observation. Regression analysis method to construct the correlation model of land subsidence and its influence factors in settlement area.The land subsidence monitoring of Zheng-Xu high-speed Kaifeng section is compared and analysed with the same period using second class precision level measurement points settlement. The results show that the method is effective and reliable.

Key words: high-speed rail, land subsidence, stratification monitoring, regression analysis
