GPS定位技术在变形监测中的应用
摘要:GPS 技术作为一种全新的现代空间定位技术,已经在许多的测量领域取代传统的光学和电子测量方法,变形监测领域也不例外。变形监测是监测形变体安全与否的重要手段,其主要任务是通过变形监测获取变形信息,然后对变形信息进行分析,对变形体的安全状况做出判断。GPS 以其高精度、全天候、自动化等诸多优点在变形监测领域得到了广泛的应用,成为大坝、大桥、滑坡以及高层建筑物变形监测中极其重要的测量手段。将 GPS 技术用于变形监测以及变形数据处理具有重要的理论意义和现实意义。
Abstract: the technology of GPS is a new modern space positioning technology, has been used in many measurement field instead of the traditional optical and electronic measuring method, deformation monitoring field is no exception. Deformation monitoring is to monitor the deformable body safety and the important means, its main task is through deformation monitoring to obtain deformation information, then the deformation information analysis, the deformation body safety status judgment. GPS with its high accuracy, all-weather, automation and many other advantages in deformation monitoring is applied widely, ing dam, bridge, landslide and high-rise building deformation monitoring plays an important role in measuring means. GPS technology for deformation monitoring and deformation data processing has the important theory significance and the practical significance.
