黄土路基客运专线沉降监测技术研究

摘要

客运专线路基作为轨道结构的基础，其沉降监测及工后沉降预测非常关键。必须对沉降观测资料进行分析以预测工后沉降、确定无碴轨道铺设时间。本文以西宝客运专线为例对黄土路基工程沉降监测工作进行了论述。%Passenger railway subgrade is the basis of track structure , it is critical that the subsidence monitoring and post -construc-tion settlement prediction .People analyze the settlement observation data for predict post -construction settlement and determine bal-last less track laying time .The paper taking Xi′an-Baoji special passenger line as an example discussed the loess subgrade engineer -ing settlement monitoring work .
