摘　　要：厂区负挖爆破、厂房±0.000 m以上结构、道路管网等施工,直接影响厂区测量控制点点位之间不通视、变形、破坏,甚至影响核电施工测量与质量。为了高效、高精度恢复厂区测量控制网,经过探讨、实践,利用无定向闭合导线测量技术进行核电厂区测量控制网点恢复,取得了良好的技术与经济效果。给核电施工期间的微型控制网复测、次级控制网点恢复或新增,以及其他项目通视条件较差、点位数量少、位置分散等影响因素的控制网施工测量提供良好的借鉴。The plant negative excavation and blasting, plant ±0.000 m above the structure, road pipeline network and other construction, directly affect the plant area measurement control points between the points of non-visibility, deformation, damage, and even affect the nuclear power construction measurement and quality. In order to restore the measurement control network in the plant area with high efficiency and precision, after discussion and practice, the measurement control points in the nuclear power plant area are restored by using undirected closed wire measurement technology, which has achieved good technical and economic results. To the nuclear power construction period of the miniature control network resurvey, secondary control network restoration or new, as well as other projects with poor visibility conditions, the number of points, the location of scattered and other factors affecting the control network construction measurement to provide a good reference.
