高速公路提级扩建中分带宽度分析

高速公路提级改扩建工程，面临着标准断面的调整，中分带是路基标准横断面的一部分，由于提级及设计规范的更新调整，中分带宽度可能面临调整。本文以某高速公路改扩建工程为例，从断面标准的一致性、行车安全、施工期间交通运营、工程造价等方面分析中分带宽度对拓宽工程的影响，意在为同类工程总结积累相关经验。

Analysis of Median Strip Width in Expressway Reconstruction and Expansion

Highway reconstruction always faces the adjustment of standard cross-section.As a part of subgrade standard cross-section,median strip may be adjusted because of reconstruction and updation of design standard.Taking a expressway reconstruction engineering as an example,this paper analyzes the influence of median strip width on the reconstruction and expansion such as the consistency of cross-section standard,driving safety,traffic service during construction period and project costs.The research could provi...
