介绍了地面沉降的危害性和常用的地面沉降监测技术,重点分析了精密水准和InSAR技术地面沉降监测成果,由分析结果可知,差异沉降监测点密度非常重要,且结果正确表达了基础设施的局部沉降特征。
The harm of land subsidence and the commonly used land subsidence monitoring techniques are introduced. The results of land subsidence monitoring based on precision leveling and InSAR technology are analyzed emphatically. From the analysis results, it is very important that the density of monitoring points of difference subsidence is very important, and the result correctly represents the part of the infrastructure Sedimentation characteristics.
