辽宁省国省干线低等级公路概况分析与改扩建设计研究

Overview Analysis of National and Provincial Arteries as Low-grade Highways in Liaoning Province and the Relevant Reconstruction and Expansion Design Research

依据公路统计资料,对辽宁省国省干线低等级公路的里程分布情况及具体类别划分情况进行了调查分析。在资料整合的基础上,总结梳理当前改扩建面临的农田、环保和资金问题,并提出改扩建总体设计、横断面设计、平面及纵断面设计、路面改造设计方面的实践经验,以期为类似工程和相关研究人员提供参考。

Based on highway statistics,the mileage distribution and specific classification of national and provincial arteries as low-grade highways were investigated and analyzed in Liaoning Province.On the basis of data integration,we summarize and sort out the farmland,environmental protection and financial problems faced by the current reconstruction and expansion engineering,and propose practical experience in terms of the overall design,cross-sectional design,plane and longitudinal section design,and pavement modification design of the reconstruction and expansion engineering,with a view to providing reference for similar projects as well as for the relevant researchers.
