摘要
高速公路与天然气管道伴行、交叉是设计工作中经常遇到的问题,在评价关于燃气管道的涉路工程和在公路的方案论证、方案设计中,需要控制住关键距离。不同工况下需要查阅不同的法律、法规、规范,一旦遗漏某项文书将对工程方案和实施造成不可挽回的损失。结合某高速公路与天然气管道伴行、交叉处置工程实例和西南地区常见的沟谷地形,形成工程经验指导工程实践。该工况复杂,包括公路依燃气管道要求采用设计方案、燃气管道依公路要求选择路由、公路与燃气管道协同设计。
Expressway and natural gas pipeline parallel,crossing is often encountered in the design work,in the evaluation of gas pipeline road-related projects and the highway program demonstration,program design,it is need to control the critical distance.Under different working conditions,it is necessary to consult different laws,regulations and norms.Once a certain document is omitted,it will cause irreparable loss to the project plan and implementation.Combined with a southwest expressway and natural gas pipeline parallel and cross disposal engineering example,the formation of engineering experience to guide engineering practice.The working condition is complicated,including the design scheme of highway according to the requirements of gas pipeline,the selection of route of gas pipeline according to the requirements of highway,and the collaborative design of highway and gas pipeline.
