  哈尔滨地铁规划九线一环的唯一环线,共设车站30座,贯穿4个中心城区,是哈尔滨市内在建规模最大、难度最高、社会影响最强的地铁项目。
 
  技术难度大:本项目关键施工技术难题富水地层基坑开挖、盾构始发和接收;近接施工;长距离下穿、侧穿历史保护建筑群;高透水砂层桩基托换施工;小间距上下叠落隧道施工等;
 
  管理难度大:投资额大,成本管理困难;线路长,协调沟通难;地下工程,防水施工质量要求高,市政工程,工期要求高。
 
  应用BIM助力哈地铁3号线完成长距离下穿、侧穿既有建筑、桥梁、隧道等重大风险源施工方案论证。通过迈达斯、ANSYS、理正等BIM软件进行深基坑工程、高支架、临时便道等方案策划、计算与优化。根据BIM模型推演施工组织设计,研究基于BIM模型的施工现场交底模式,对工期、工法、资源投入、施工工艺和安全质量要求等内容进行三维交底。
