  西十一条路中段拓宽改造工程位于牡丹江市中心城区南侧,属爱民辖区。线路总体呈西北-东南走向,起始于兴中路,沿牡丹江市高级中学西南侧通过,道路两侧多为棚户区、汽修厂、教育用地以及市场等。该道路依次穿越滨绥铁路、牡丹江车站编组站后,衔接西平安街。该道路现宽30M左右,水泥混凝土路面。拓宽改造后标准路幅宽度为60.0m。拓宽后道路与黄花路及滨绥铁路交叉处均采用下穿立交桥式。主线改建道路路段全长1.4km左右,设计车速为40km/h,双向八车道。
 
  顶进施工时如何保证上部结构不破坏,控制顶推过程中地面沉降变形是本工程的重点。纵横抬梁支撑体系结构复杂计算难度大。
 
  项目采用基于BIM模型的数字化建造模式,利用Revit、Civil3D、Dynamo等软件对船槽、道路、框体、机电等多专业进行参数化建模,在以往工程中船槽、框体等工程量计算是难点,利用BIM技术在模型中精确的提取,大大提高了工程量计算速度和精度,实现一模多用。利用BIM的可视性,观察工程项目与既有管线之间的关系,解决管线碰撞问题,为施工提供最优的实施方案,通过NAVISworks软件模拟现场施工进度,更直观的反映项目进度计划的落实情况。编组站下框体顶进施工是本项目中最大的施工难点,针对这一难点,将施工方案结合3D动画模拟预演,方案具体实施过程一目了然,对工人进行可视化交底,确保现场顺利实施。并通过手机端的应用让所有项目参与人随时随地查看视频交底。
