项目概览

项目

拥有每天近80000的车流量和来自五个不同方位的庞大客流量，这座通向巴西圣保罗里贝朗普雷图的主要立交桥入口曾是无数撞车事故的事发地，亟待重建。圣保罗市政府投资1.2亿里尔启动该项目，对环岛进行重新配置，并且沿用Beta 2 Engenharia (Beta 2)来设计能够满足未来30年交通需求的道路网。为快速高效地确定最优几何设计解决方案，Beta 2 要求得到集成的土建设计以及分析解决方案。

解决方案

Beta 2 在巴西的项目上应用了PowerCivil，并采用RM Bridge，基于对其与当地道路系统的兼容性、最少征用数量、对当前电流的最小程度的破坏以及对排水、污水及其他公用事业的调整这些方面的考虑，分析每一设计备选方案的效果。Bentley的土建设计应用软件使该项目团队能够快速而准确地共享、分析所有设计方案，以确定最优的几何形状和结构重新配置。最终的重建方案将路面扩展到11800米，包括总高度630米的8座高架桥以及20个入口坡道，以避免相连道路的交通交织在一起。

项目成果

巴西项目上PowerCivil的应用以及RM Bridge的应用改善了不同设计团队之间的协调与合作，促进了工程优化方案的选取，使Beta 2 能够快速高效地完善其几何形状和结构设计。Bentley软件的综合分析和设计能力与现代施工技术的完美结合使得该项目早于原计划4个月交付。新建成的立交桥将改善交通流量、大大减少交通事故的发生，并且使超过150万的旅客受益。

软件

 在巴西的项目上，Beta 2 应用PowerCivil从最初的概念阶段到最终的几何形状阶段快速、动态地分析每个设计备选方案的效果。作为多功能工作平台，该应用软件加速了信息流动、优化了准备和生成报告的时间、记录了数据显示偏好，并计算出了地面平整度。RM Bridge使项目团队能在很短时间内对高架桥进行测量，同时其参数化建模功能让设计师能够插入修改并自动对结构做出相应调整。

Outcome/Facts
  • Beta 2 used Bentley road and bridge modeling and analysis applications to quickly and efficiently evaluate numerous design alternatives to determine the optimal geometry and structural design for the reconfiguration of the obsolete interchange access to Ribeirão Preto, São Paulo, Brazil.
  • With eight viaducts totaling 630 meters and 20 access ramps, the perfected design solution extended the roadway by 11,800 meters to enable 80,000 vehicles to access and navigate the area daily.
  • Using Bentley software improved efficiencies enabling the team to deliver the project four months ahead of schedule.
  • The BRL 120 million roadway reconstruction will significantly reduce the number of accidents, decrease travel times, and meet vehicle demands for the next 30 years.
Quote:

  • The use of Bentley PowerCivil for Brazil and RM Bridge allows project companies that operate in the transportation area to optimize and improve the quality of their works, which decisively contributes to the community’s improvement through more efficient projects and with more reduced costs. In addition, it allows professionals to technically evolve, exploring all the qualities of the materials used.
