摘要
内蒙古赤峰市三座店水利工程地处一个特殊的地理位置,控制网的基准点坐标属于1954年北京坐标系高斯正形投影3°分带的40带坐标(中央子午线东经120°).为了保证施工放样顺利进行,从外业数据采集和内业数据处理方面,须最大限度地保持施工控制网与现有地形图平面坐标系统的一致性.网内控制点位于工程建设的必要位置,均具有足够的平面精度和高程精度,完全满足工程施工测量对控制网的精度要求.
The Three Stores Hydraulic Project lies in a special geographical position, in Chifeng City of Inner Monqolia. The controlling net＇s dot＇s coordinate belongs to the 40th three degree （E120°） of Beijing coordinate＇s Gauss-kruger projection, 1954. To make sure the work be in progress successful, we collected data of outside work and data processing of inside work, keeping the controlling net of construction in accord with the system of the coordinate of the relief map mostly. There were some dots of the controlling net in the necessary position. With sufficient precision of the level and elevation, these dots can satisfy the controlling survey of construction in this project.
