摘要
根据黄登水电站枢纽区水工建筑物、边坡监测需要,结合现场通视条件、利于使用和保护,且点位相对稳定等因素,设计了平面变形监测控制网。采用基于最小二乘法原理的精度估算方法进行优化设计,最终选定了62条边、124个方向构建监测网。结果表明平面变形监测控制网具有高精度、高可靠性和高灵敏度的特点,可作为平面变形监测的基准。最后,提出了变形监测控制网观测、数据处理的技术指标和要求。
According to the needs of hydraulic structures and slope monitoring for Huangdeng hydroelectric station,this paper designs a plane deformation monitoring control network,combined with the factors of visibility conditions,benefit to use and protection,and spotting is relatively stable,etc.,then by using the least squares method to optimize the design.We selected 62 sides and124 directions.Results show that the plane deformation monitoring control network has the characteristics of high precision,high reliability,and high sensitivity,can be used as the datum for plane deformation monitoring.Finally we proposed the technique index and requirement.
