新疆三莎高速公路盐渍土路基变形监测

Deformation Monitoring of Salty Soil Subgrade of Sansha Expressway in Sinkiang

为了解盐渍土路基的变形规律,以新疆三岔口至莎车高速公路为例,通过对路基变形监测原理的研究,确定了监测点布置、监测方法及监测精度,选取了监测仪器、设备,限定了监测报警值,并选取典型监测断面对监测结果进行了分析,可为喀什地区类似公路项目提供参照,为在新疆及其他盐渍土地区应用打下基础。

In order to understand the deformation law of sahy soil subgrade, taking Sanchakou - Shache Expressway in Sinkiang as an example, the arrangement of monitoring point, monitoring method and monitoring accuracy are determined through the research on the principle of subgrade deformation monitoring, the monitoring instrument and equipment are selected, the monitoring alarm result is made by selecting typical monitoring section, so as Kashi Prefecture and lay a foundation for the application in S value is limited, and the analysis on the monitoring to provide reliable reference for highway project in inkiang and other salty soil regions.
