摘　　要：利用单频接收机和双频接收机对顺溪滑坡的监测点分别进行监测,结合全站仪测得的基准点相对监测点的基线长度对观测数据进行处理和分析,总结出对基线较短的控制网采用单频接收机进行监测可以得到采用双频接收机进行监测的效果,不仅节约工程成本,而且在进行周期性复测时操作方便。We can make use of single-frequency receiver and dual-frequency receiver to monitor monitoring points on Shunxi landslide, then process and analyse the data combined with the relative baseline from datum point which is measured by total station to monitoring point. Finally, we can get the conclusion that better precision will be achieved when we use single-frequency receiver on control network of short baseline, at the same time, not only saving the engineering cost, but also making it easy to operate when conducting periodic re-testing.
