针对三峡垂直升船机高薄壁塔柱结构混凝土形体及内置埋件施工精度指标要求,对三峡升船机塔柱混凝土及内置埋件施工测量中的平面、高程基准传递及埋件定位测量方法进行了研究。分别将天顶仪投点、电磁波测距及中心带照准标志的圆柱螺帽型定位装置施工测量技术运用于混凝土结构尺寸控制测量以及内置埋件定位测量。通过对实测数据的统计与分析,证明三峡升船机塔柱混凝土施工测量技术方案具有可靠性和可行性。
針對三峽垂直升船機高薄壁塔柱結構混凝土形體及內置埋件施工精度指標要求,對三峽升船機塔柱混凝土及內置埋件施工測量中的平麵、高程基準傳遞及埋件定位測量方法進行瞭研究。分彆將天頂儀投點、電磁波測距及中心帶照準標誌的圓柱螺帽型定位裝置施工測量技術運用于混凝土結構呎吋控製測量以及內置埋件定位測量。通過對實測數據的統計與分析,證明三峽升船機塔柱混凝土施工測量技術方案具有可靠性和可行性。

Three Gorges Project vertical ship lift is high-walled tower structure. According to the preci-sion requirements of construction for concrete body and built-in embedded parts,the plane,elevation datum transmission and positioning measurement methods for embedded parts in construction survey of concrete and built-in embedded parts of Three Gorges Project ship lift tower were studied. The construction survey technolo-gies,including zenith telescope planar cast point,electromagnetic distance measuring and cylindrical nut type positioning device with a sighting mark in center are applied to size-control measurement for concrete structure and positioning measurement for built-in embedded parts respectively. Through the statistical analysis on the mea-sured data,the construction survey technology solutions for concrete construction of Three Gorges Project ship lift tower are proved to be reliable and feasible.
