1、一、分部工程概况：东莞市常虎高速公路位于东莞市东南部，是广东省规划的高速公路网络的重要组成部分，也是珠江三角洲腹地一条东西快速通道。路线西起东莞虎门镇，接珠江口港口群，并与广深高速公路、虎门大桥东引道相接，东至东莞常平镇（往东延伸可接惠盐高速公路和广惠高速公路）。1.1九江水特大桥为常虎高速公路主线上桥梁，双向6车道，位于22标段K45+050~K46+900范围内,起点桩号为K45+187.092,终点桩号为K45+734.652，桥梁全长547.56。本桥平面位于R-1200m右偏圆曲线，A-600m的缓和曲线及直线上，沿线跨越
2、东深渠与东深公路，与东深公路交叉桩号为K45+681.215，交角为68°21′32″。1)主要技术指标（1）桥面宽度：基本宽度为35m=左幅桥（17.25m）+0.5m+右幅桥（17.25m）单幅桥宽17.25m=0.5m(护墙)+16m（行车道）+0.75m(护栏)左幅桥在K45+540~610范围内由17.25m渐变到20.5m。（2）桥面纵坡：桥梁位于0.5%的上坡段(3)桥面横坡：由6%单向坡过渡到2%双面坡(4)桥下净空：净高：大于5.0m(上跨东深公路)2)结构形式（1）上部构造Adheredtocomprehensi
