茶林坪乌江大桥无塔缆索起重吊机锚索式主锚碇关键技术研究

摘要

Based on the engineering condition of Wujiang River Bridge in Chalinping, which is a V-shaped valley, the construction plan is adjusted by canceling the tower frame of cable system and optimizing back anchorage system to establish non-tower cable crane layout and anchorage-cable system. The structural form of anchorage beam and main anchorage cable is elaborated and the design and key construction techniques of pre-stressed anchor-age-cable fixation technology are summarized.%文章介绍了在V型峡谷地形地质条件下结合工程实际情况，设计重庆茶林坪乌江大桥拱肋安装施工方案时取消了缆索系统塔架并优化了后锚碇体系，形成了无塔缆索吊机总体布置与锚索式主锚碇体系，阐述了锚梁与锚索式主锚碇锚索结构形式，总结了预应力锚索锚固技术的设计与施工关键技术。
