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
