从工程地质角度考虑吴起至定边高速公路选线方案比选

Wuqi-Dingbian Highway Line Selection From Engineering Geological Perspective

随着我国公路建设的进一步加快,东部地区公路网已逐步完善,中西部地区公路建设还正在进行中,我国地域辽阔、地形复杂多样,尤其是中西部地区,高原山地众多,对公路选线增加了一定难度。良好的公路路线方案除了使路线平面、纵断面和横断面各设计指标得到综合应用,节约工程造价,确保行车安全外,还应注意沿线地质病害情况。文章结合吴起一定边高速公路选线过程,运用地质选线方法从工程地质角度考虑进行方案比选,并得出最佳方案。

With the further acceleration of highway construction in our county, the road network in the eastern region has been gradually improved, road construction is still under way in central and western regions, China＇s vast, complex and varied terrain, especially in central and western regions, large numbers of plateaus and mountains lead to a certain degree of difficulty in the design of the alignment of highway. Good highway programs, in addition to the design specifications such as the road surface, profile and cross sections are comprehensive applicated, saving construction costs and ensuring road safety, the geological diseases should be noted.In this paper, geological road alignment is used in Wuqi-Dingbian highway routing process, chosing the best alignment scheme.
