美国休斯敦市区GPS沉降观测站布设实例研究

随着城市建设的快速发展,大量的城市地下水、矿产资源被大规模的开发和利用以及城市高层建筑建设,导致城市地面沉降危害日益显著,及时的掌握和了解地表沉降情况,是预防城市环境沉降危害的关键,本文提出采用GPS测量技术的地表沉降观测站的研究和设计,通过在美国休斯敦大都市采用构建地表沉降观测站,对地表沉降进行全天候观测和数据采集,为分析美国休斯敦大都市地表沉降变化规律,对城市环境沉降危害预测提供了准确的观测数据支持.

Case Study on GPS Subsidence Observation Station in Houston Metropolitan Area

With the rapid development of urban construction, a large number of urban groundwater, mineral resources were u-tilized.The danger of land subsidence caused by construction of high-rise buildings and urban construction became increasingly significant.To grasp and understand the situation of surface subsidence, prevent the key settlement harm, this paper presents a measurement using GPS technology research based on results from subsidence observation station in Houston metropolitan area.Through collecting data on its surface subsidence, the surface subsidence characteristics in Houston were analyzed to provide ac-curate data support for observation.
