天津市地面沉降监测技术应用及发展建议

The suggestion and application of land subsidence monitoring in Tianjin

地面沉降监测是防治研究工作的基础,适当的监测方案可以及时准确反映地面沉降地质灾害发育情况。本文介绍了天津市地面沉降监测三十多年发展历程及应用现状,对水准测量、GPS监测、In SAR监测和分层标等监测手段进行对比论述,分析其适用性,并对地面沉降监测工作未来发展提出建议,为其他地面沉降灾害发育地区选取合理的地面沉降监测方案提供参考。

Monitoring is the basis of land subsidence research and control.The status of land subsidence can be obtainedaccurately and on a timely basis by applying an appropriate monitoring scheme.This article presents the course ofdevelopment and application of land subsidence monitoring in Tianjin over a period of more than30years.The applicabilityof level monitoring,GPS monitoring,InSAR monitoring,and layered benchmark monitoring methods are analyzed andcompared.Recommendations for the development of land subsidence monitoring for the future are made,and a referencefor the selection of a monitoring scheme for other land subsidence disaster areas is provided.
