山区因为受地形地势、水文条件等因素的影响,在修建高速公路的时候往往需要修建相应的配套桥梁设施,山区的地势起伏比较大,地面条件比较复杂,像是,滑坡、泥石流、崩塌等灾害常有发生,所以说,在山区修建高速公路的时候经常需要建设相应的桥梁作为辅助,本文就来研究一下山区高速公路的桥梁设计问题。 Due to the influence of topography, hydrological conditions and other factors, mountainous areas often need to construct corresponding supporting bridge facilities during the construction of expressways. The ups and downs in mountainous areas are relatively large and the ground conditions are complicated. For example, landslides, mudslides, landslides and other disasters Therefore, it is often necessary to build a corresponding bridge as an aid in the construction of expressways in mountainous areas. This article will examine the bridge design of mountainous expressways.
