| 摘 要： | 小浪底水利枢纽工程洞群部分包括导流洞、明流洞、排沙洞、发电洞、孔板洞、灌溉洞等各种隧洞108条。洞群施工控制网是在小浪底GPS首级控制网的基础上布设的，为便于施工和快速放样，首先建立以每条遂洞轴线为北方向的坐标系，并将隧洞原设计采用的国家大地坐标转换为每条隧洞的施工坐标。在开挖测量中，用全站仪配合CASIO fx-4800机算器，计算超欠挖及隧洞拱顶变形值。为保证隧洞施工与设计一致，在断面测量中还使用了瑞士徕卡公司新生产的AMT3000激光无棱镜断面仪，大幅度提高了工作效率：

| Abstract: | The tunnel group of Xiaolangdi hydro-junction project includes 108 tunnels for diversion,free-flow,desilting,power generating,orifice plate and irrigating.Tunnel group construction control net is laid out on the basis of Xiaolangdi GPS first-order control network.For convenient and fast setting out,firstly established a coordinates system of to take every tunnel axis as northward,transformed national geodetic coordinates which is original tunnel design adopted into every tunnel's construction coordinates.During the excavation surveying,total station and Casio FX-4800 calculator were used to calculate the overbreak,underbreak and tunnel vault deformation values.To ensure consistency of tunnel construction and design,the Swiss Leica newly produced AMT 3000 laser prismless profiler was used in cross-section surveying,thus raised working efficiency greatly. |
