龙羊峡水电站位于青海省的龙羊峡谷进口处,河床狭窄,地形陡峭(河底宽约40米,岸坡为60°左右),在这样的地形条件下进行施工测量,劳动强度大,效率低,又不安全。为了解决这一问题,从1976年起,在领导和有关部门的支持下,引进了一批新设备和新技术, Longyangxia Hydropower Station is located at the entrance of Longyang Gorge in Qinghai Province. The riverbed is narrow with steep terrain (the width of river bottom is about 40 meters and the bank slope is about 60 °). Construction surveys are carried out under such terrain conditions. The labor intensity is large and the efficiency Low, not safe. In order to solve this problem, from 1976, with the support of the leaders and relevant departments, a number of new equipment and new technologies were introduced,
