【摘要】：兼具科学性和艺术性的公路选线设计对个人经验依赖较大,虽然随着工程实践和人们认识的不断深入和进步,设计理念也从选线地质逐步深化到地质选线,但仍未完全形成系统的方法论。本文通过对部分路线设计案例的成功经验和失败教训的归纳和总结,并结合多年路线设计的经验,提炼出"服务功能和承载能力相协调、自然生态可持续发展、控制因素的系统综合分析、最差的地质条件控制路线方案(‘木桶’原理)、重大工程地质问题否决路线方案、综合选线与整体最优"等公路工程地质选线基本原则,总结出按"以服务功能草定路线走向→宏观识别、碎部研判,优选路线走廊→走廊带工程地质条件综合评估→根据地形条件初拟路线方案→结合工程地质修订确定推荐线位→推荐线位的工程地质条件评价→推荐线位的比选和修订"程序进行地质选线工作的一般程序和定性研究基本方法。
[Abstract]:The design of highway route selection, which is both scientific and artistic, relies heavily on personal experience, although with the deepening and progress of engineering practice and people's understanding, the design concept has gradually deepened from route selection geology to geological route selection. However, the methodology of the system has not yet been fully formed. By summing up and summarizing the successful experience and failure lessons of some route design cases, and combining with the experience of many years' route design, this paper abstracts out the "harmonious service function and carrying capacity, and the sustainable development of natural ecology." The basic principles of highway engineering geological route selection, such as the systematic comprehensive analysis of control factors, the worst control route scheme for geological conditions ('barrel' principle), the rejection of route schemes for major engineering geological problems, the integrated route selection and overall optimization, etc. Summed up according to the "service function to draft a route towards macro identification, the department study," Comprehensive Evaluation of Engineering Geological conditions in the Corridor and Corridor Zone of optimal selection / determination of the Engineering Geological conditions of recommended Lines and recommended Lines according to the preliminary Route Scheme of topographic conditions and the revision of Engineering Geology and the comparison of recommended Line sites with the Evaluation of Engineering Geological conditions in the Corridor and Corridor Corridor The general procedure of geological route selection and the basic method of qualitative research.
