摘要
文章结合天峨至凤山公路三岗岭路段工程实例,从建设规模及工程造价、运营期管养费用与社会效益两个方面出发,对原施工图阶段的越岭线方案与实施过程中变更的隧道方案进行比选分析,为类似工程项目研究提供借鉴。
Combining Tian＇e-Fengshan Highway Sangangling section engineering practices,and starting from the construction scale and construction costs as well as the maintenance cost during operation period and social benefits,this article compared and analyzed the ridge-crossing line program at origi-nal construction drawing stage and the modified tunnel program during implementation process,thereby providing the reference for the study of similar projects.
