摘    要:武汉阳逻长江大桥主桥为主跨1280m悬索桥。北锚碇采用放坡大开挖深埋扩大基础实腹式锚体重力式锚;南锚碇采用支护开挖深埋圆形扩大基础框架式锚体重力式锚,其基坑工程采用外径73m、壁厚1.5m、深61.5m、最大挖深45m的圆形地下连续墙加内衬的支护结构型式;在国内首次研究应用了可换式预应力锚固系统。本文概述了锚碇设计总体构造、可换式预应力锚固系统研究及其设计技术特点。

关 键 词:阳逻长江大桥  锚碇  可换式预应力锚固系统  圆形地下连续墙

Abstract:Wuhan Yangluo Yangtze River Bridge is a main span 1280m suspension bridge. The north anchorages adopt sloping large excavation deep buried expanded foundation solid web anchor weight type anchor; south anchorages adopt supporting excavation deep buried circular expanded foundation frame anchor weight type anchor, the pit project adopts 73m outer diameter, 1.5m wall thickness, 61.5m depth, maximum excavation depth of 45m circular diaphragm wall plus liner support structure type; in the country for the first time to study and apply the exchangeable pre-stressing anchorage system. This paper summarizes the overall structure of anchor design, the study of interchangeable prestressing anchorage system and its design technology characteristics.
