基于DInSAR技术的沉降监测与分析及在铁路保护煤柱安全留设可靠性方面的应用研究

Monitoring and analysis of settlement technology and research on application of protecting coal pillars retention reliability in railway safety based on DInSAR

文中结合传统水准测量成果,利用DInSAR技术的沉降监测与数据对比分析,进行铁路保护媒柱留设及铁路安全性可靠性研究。传统的地表形变监测方法工作量大、成本高、易受天气和实地地表情况的制约。采用DInSAR非接触式的遥感手段技术,动态获取高精度的采动区铁路时序形变,对于保障铁路通行安全具有重要的理论和实际意义。

Combining with the results of traditional leveling surveys,using DInSAR technology for settlement monitoring and data comparison and analysis,studies on the railway protection medium pillars and the railway safety and reliability were carried out.Traditional surface deformation monitoring methods had a large workload,high cost,and was easily constrained by weather and ground conditions.DInSAR non-contact remote sensing technology was used to dynamically obtain high-precision railway time series deformation in mining area.It had important theoretical and practical significance for ensuring railway traffic safety.
