摘要
结合鄂北地区水资源配置项目中的宝林隧洞工程,对引水隧洞洞内平面控制网的布设方案进行了分析。设计了单一导线法、交叉导线法和连续自由设站法3种布设方案,并针对前2种方法加测了陀螺方位角,将其作为新增观测量进行联合平差,得到最优布站方案,用于指导工程施工。
Focusing on the Baolin Tunnel Project of Water Resources Allocation Project in the north of Hubei Province,project design and analysis of inner horizontal control network for underground water tunnel are introduced.Three kinds of control networks are designed：single-traverse method,cross-traverse method and continuous free-station method,gyro azimuth for the first two methods is also measured,which is used as a new observation for the combined adjustment,then we get the optimal network layout for guiding the construction of project.
