摘要
结合省内外多处高速公路互通立交收费车道扩容改造工程,总结收费车道扩容改造工程中的关键技术问题,系统研究收费车道数的计算与确定、路基路面加宽方式及衔接工艺、收费广场前后立交匝道线形优化以及收费天棚的处置方式等关键问题的处置措施。
Based on the some expandable engineering of interchange toll lane,the pivotal technical problems in the engineering are summed up.Then the construction technique of the problems are analysed,including the toll lane count, the splicing technique of the new and old subgrade , the geometric design in interchange ramp between the toll plaza ,the technical measures of sun shade.
