Abstract
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.关键词
