集约用地技术在徐明高速公路中的应用

Application of Intensive Land Use Technology in Xuming Expressway

平原区大量分布宝贵的耕地资源,高速公路建设中应大力推广集约用地技术。集约用地技术经过多年的发展,已形成不少行之有效的成果。通过徐明高速公路安徽段的建设经验,主要探讨低路堤设计技术(含下挖式通道技术、低高度梁技术)和路基瘦身技术(中分带宽度优化、边沟优化、支挡结构瘦身等)在高速公路中的应用,并对应用效果进行量化分析,以期对集约用地技术的进一步推广应用提供些微助益。

There are a large number of valuable cultivated land resources in plain areas.Intensive land use technology should be vigorously promoted in highway construction. After years of development,intensive land use technology has formed many effective results.Based on the construction experience of Anhui section of Xuming Expressway,this paper mainly discusses the application of low embankment design technology(including undercut tunnel technology,low-height beam technology)and subgrade thin technology (medium-width optimization,side ditch optimization,support structure thin-weight,etc.)in expressway,and quantitatively analyses the application effect in order to further promote the application of intensive land-use technology and provide a little help.
