岩溶地区公路地质选线方法

Route Selection Method for Highway in Karst Area

为提出合理的岩溶区公路选线方法,以降低工程造价、减少工程病害及环境影响、科学地解决穿越与避让问题,通过研究喀斯特地区岩溶发育的常规规律、岩溶现象对公路工程建设的影响以及岩溶地区公路规划选线的相关要点,分析得出不同岩溶地区的选线原则。提出在岩溶区公路选线的过程中要遵守"多比选,慎选择"的原则和"以避为主,避重就轻"的设计要点,对岩溶地区公路选线具有重大指导意义。

In order to propose a reasonable route selection method for highways in karst areas, so as to reduce project cost, reduce engineering diseases and environmental impact, and scientifically solve the problem of crossing and avoidance, the principle of route selection in different karst areas was proposed by studying the general laws of karst development in those areas, the impact of karst phenomenon on highway project construction and the key points of highway planning and route selection in karst areas. It was suggested to make as many comparisons as possible and choose carefully and to take up the minor issue to evade the major one during the process of route selection, which provides a meaningful guidance to such a task in karst areas.
