铁路节能环保与安全卫生

InSAR技术具有覆盖范围广、全天候、低成本等优点，已广泛应用于不同行业地面沉降监测与分析。采用SBAS-InSAR技术对铁路项目弃渣场、施工便道等水土流失重点区域进行地表形变监测，获取地表形变信息，分析地表形变速率和累计沉降量，并进一步计算得到研究区土壤侵蚀量及土壤侵蚀模数等数据。该技术实现了铁路项目建设期重点区域水土流失监测、土壤侵蚀量计算，有效提升了铁路项目水土流失监测时效与精度。

The InSAR technology boasts such advantages as extensive coverage, all-weather operation, and low cost. It has been widely utilized in the monitoring and analysis of ground subsidence across diverse industries. This paper employs the SBAS-InSAR technology to monitor the surface deformation in key areas susceptible to water and soil loss, such as the spoil grounds of railway projects and construction access roads. The surface deformation information is acquired, the surface deformation rate and cumulative settlement are analyzed, and the amount of soil erosion that has been eroded and displaced within the unit area of the study area is further deduced. The monitoring of water and soil loss in key areas during the construction period of railway projects and the calculation of soil erosion quantities have been accomplished, significantly improving the timeliness and accuracy of water and soil loss monitoring for railway projects.
