Research on Monitoring Technology of Surface Subsidence for 500 kV Substation and Its Application

摘要:

为实现多模式地表缓慢沉降监测技术并提高监测预警的成功率，论述了基于INSAＲ 遥感监测、光纤传感监测 和地质雷达地表无损监测等监测技术的研究及应用。以四川省甘孜州某500 kV 变电站地面沉降为例，结合实地野外 调查，对空间监测数据进行效果分析，验证了此监测方法的可行性和准确性。

Abstract:

In order to realize the multi － mode monitoring technologies for transmission channel land subsidence and improve the success rate of monitoring and early warning，the space monitoring system is established，including INSAＲ remote sensing， optical fiber sensing and non － destructive surface monitoring with geological radar． Based on the ground subsidence of a 500 kV substation in Sichuan province，the feasibility and accuracy of the proposed monitoring system are verified by field investigation and the effect of monitoring system．
