摘　　要：测量机器人在水库大坝长期、连续、自动的位移监测中发挥着重要作用,然而其监测结果的可靠性易受大气折光的影响。在理论分析气象元素修正、基准点差分修正等模型的基础上,利用碗米坡电站建立的基于测量机器人的自动化监测系统,对大气折光修正模型的适用性进行了试验分析。结果表明,对于小监测区域,仅利用测站处的气象信息进行修正即可取得较好的效果,同时基准点差分修正与气象元素修正的结果精度相当。结果对于构建基于测量机器人的大坝自动化监测系统具有参考价值。Robotic total station plays an important role in long-term,continuous and automatic displacement monitoring of reservoir dams.But the reliability of the monitoring results is easily affected by atmospheric refraction.Based on the theoretical analysis of the meteorological correction model and reference point differential correction model,the applicability of atmospheric refraction correction model was experimentally analyzed by using the automatic monitoring system based on robotic total station established in Wanmipo power station.The results show that for small monitoring areas,only using the meteorological data at the station for correction can achieve good results,and the accuracy of reference point differential correction model is equivalent to that of meteorological correction model.It has reference value for the construction of dam automatic monitoring system based on robotic total station.
