主线桥、匝道桥墩身施工方案

1、1概述1.1 工程概况武青三干道立交位于武汉天兴洲公铁两用长江大桥南岸，立交主线（ZHUX）为规划三环路，即天兴洲大桥南岸公路引线。在本标段施工范围内，主线起点桩号为ZHUXK15+042.5，止点桩号为ZHUXK16+557.5（与正桥里程系统一致），接青化路立交主线，全长1515米。本立交由主线高架桥，被交路武青三干道，11条匝道桥梁（路堤），南北两侧的铺道及一座人行天桥共同组成。立交桥工程内容按武青三干道立交道路工程总体布置，立交桥梁工程包括：主线桥（即长江四桥公路引桥南岸主线高架桥）及WB、WC、WD、WE、WF、WG、WI、WJ、WK、WL共十条匝道桥以及立交人行辅道跨匝道的一座跨线

2、桥。主线桥桥墩（单幅桥）根据桥面宽度不同（单幅桥）分别采用双柱墩或三柱墩，墩柱共219个，截面尺寸分别为11001100mm和14001400mm，圆弧导角均为R=25mm的方柱墩，墩柱高度4.466m10.743 m。 匝道桥桥墩（单幅桥）根据桥面宽度不同分别采用圆形截面独柱或双柱桥墩共158个墩柱，其中1000mm的92个，1200mm的60个,1600mm的6个。墩身高度为1.7m8.2m。1.2 立交桥墩（柱）身参数 主线桥墩柱参数表 表1归属联左右线里程桩号墩号根数设计承台顶标高 (m)设计墩柱顶标高(m)墩身尺寸(m)设计墩身C30砼方量(m3)墩帽高度（m)设计墩帽C30砼方量(
