公路隧道的大多数指南和标准都是所谓指示型的,即它们详细告诉工程师应如何建造安全的隧道。然而,建筑规范现在的发展方向是以性能化为基础的规范(performance-based codes),即给工程师更大的灵活性,以便提出新颖的解决方案。在复杂的新型建筑项目中,这种规范既可节省资金,又可提高建筑的安全性。瑞典的一个研究组已研发出隧道性能化设计的方案。1公路隧道性能化设计指南方案瑞典SP技术研究所和Lund大学最近为瑞典交通局(STA)撰写了一个公路隧道性能化设计指南的方
Most guidelines and standards for highway tunnels are so-called indicative that they tell engineers in detail how to build a secure tunnel. However, building codes are now moving toward performance-based codes, giving engineers more flexibility to come up with new solutions. In complex new construction projects, this kind of norms can save money, but also improve the safety of the building. A research group in Sweden has developed a tunnel performance-based design. A Road Tunnel Performance Design Guide Scenario The SP Institute of Technology and Lund University recently wrote a guide to a road tunnel performance design guide for the Swedish Transport Agency (STA)
