摘要
葛洲坝水利枢纽平面监测网进行过多期观测,实测效果并不理想,网形强度弱,可靠性因子和主要监测方向的灵敏度低。通过模型分析,在真空激光准直系统改造的基础上,探讨用全球定位系统(GPS)技术改造旧网,进行网形优化,以提高枢纽平面监测网的精度、灵敏度和可靠性。
The plane monitoring-network of Gezhouba Hydroproject has been used for many times, and the measurement effects are unsatisfied. The intensity of the network is weak, the reliability and the sensitivity for the main monitoring direction are low. Based on the vacuum laser collimation system, and by model analysis, this paper discusses the application of the GPS technique to the reconstruction and optimization of the old network, so as to improve the precision, sensitivity and reliability of the monitoring network of the hydroproject.
