摘要:The short-line precast segmental concrete bridge is a concrete bridge which assembles the concrete segments made in advance by the factory through reliable connection, the key of its construction is the linear control in the prefabrication stage, generally, six point coordinate control system is used in cooperation with total station. In this paper, a new four-point distance control system is proposed to coordinate with the level gauge and steel tape for the linear control in the prefabrication stage, which has the advantages of high efficiency, simple operation and no need of measuring tower and target tower, etc. It has been successfully applied in the prefabrication stage of the main beam of the non navigable span bridge of Yueqingwan bridge, which can be used for reference in related projects.
