摘要
随着交通、建筑等工程的快速发展,高切坡数量急剧增多,其安全性备受关注,对其进行变形监测意义重大.GPS监测具有精度高,受环境限制小,易操作等特点,但由于成本较高,在工程实践中应用较少.本文分析总结了目前国内外边坡变形监测的主要方法,阐述了GPS监测方法,通过三峡库区巴东高切坡监测实例分析,结果表明,GPS观测精确可靠,精度可达毫米级,可有效监测地表变形.同时,指出了GPS用于监测实践中应注意的相关问题.
With the rapid development of engineering like transportation, construction and so on, high cut slope becomes more and more dangerous. So it is of great significance to monitor its deformation. GPS monitoring has many advantages, such as high precision, small limitation, and easy operation. Because of its high expenses, GPS monitoring practice in projects is limited, and obtains little experience and lessons. The paper summarizes the domestic and foreign primary means of deformation monitoring in high cut slope at present, outlines the method of GPS monitoring and gives one example of monitoring with the conclusion that due to its mm-level accuracy and good reliability, GPS monitoring is a highly effective means of ground deformation monitoring and has extensive application prospects. At the same time the paper puts forward some points in practice, which may guide the future GPS monitoring.
