摘要
利用乌东德水电站工程中对导流洞的开挖放样、采用岩壁上布设控制点,对各种自由设站的数学模型进行了探讨,介绍了自由设站在乌东德水电站导流洞施工测量中的具体实施方法及应用,并提出了自由设站法的测量优势,测量精度满足规范要求。
By application of the excavation setting of the diversion tunnel and the control points arranged on the rock wall of Wudongde Hydropower Project, the specific implementation methods and application of free station in the construction surveying of the diversion tun- nel of Wudongde Hydropower Project are introduced. Furthermore, the surveying advantages of the free station are proposed. The survey- ing precision satisfies the requirements of specification as well.
