GPS技术在采空区上方滑坡变形测量中的应用

Application of GPS Technology to Measure the Deformation of Landslide on the Top of the Work-out Section

在采空区上方进行滑坡变形测量,由于受采空区的影响,用传统的测量方法监测,将面临转站多、误差大、监测时间长等不利因素。介绍了GPS技术在采空区上方滑坡变形测量中的应用情况,实践证明,该方法完全能够满足规范的要求,并能做到节约人力物力、计算简便、快速。

It is difficult to find out the stable location to inbuilt the base point of monitoring because of the work-out section＇s influence during the measuring of landslide deformation on the top of it. Hence there are some disadvantages for the traditional measurement to monitoring, such as many times of transferring the monitoring station, more accumulated errors and long time to monitoring etc.. The application of GPS technology to measure the deformation of landslide on the top of the work-out section is introduced. From experiences, it is shown that by using the GPS technology to monitoring the landslide on the top of the work-out section, the specification＇s requirements can be satisfied, which is economical, calculation convenience and high efficiency.
