本文根据山区沿河公路水毁特点,结合沿河路线设计方案比选,通过合理选择平面线型指标、减小沿河路基陡坡高度,探讨沿河路线设计的关键问题:同时依托工程实例,提出了沿河陡坡路基处理方法及路基防护措施,为山区沿河公路设计与施工提供有益参考。 Based on the characteristics of water damage in the rivers along the rivers in mountainous area and the comparison of the design of the route along the river, this paper discusses the key problems in the design of the river course by reducing the height of the steep slope along the riverbed by choosing the plane linear index reasonably. At the same time, The treatment of embankment along the steep slope and the roadbed protection measures provide useful references for the design and construction of the river along the river in mountainous areas.
