【摘要】：我国高速公路通车里程己居世界第一,高速公路建设理念也从技术经济指标为重,转变为安全、环保、协调、经济、舒适和以人为本。在新的公路建设期,公路工程不仅要满足通行功能,还应符合安全、舒适、美观、环保等要求,如何处理好公路发展与环境和谐、资源利用的关系,是公路建设面临的重要课题。由于缺乏配套理论的指导,设计、施工人员面临了很大的困难。公路的背景为富有变化的自然、半自然或人工景观,路堑作为公路主体与其背景的过渡,需要作为重点来进行研究,形成科学完善的理论来指导路堑设计。但是,围绕这项工作的研究非常之少。通过本课题研究,建立合理的路堑设计与环境协调设计相结合的解决方案,体现路堑设计的稳定、协调、自然、美观、经济核心理念,为公路设计方案的优化提供一定的支持。本文主要内容如下：1、阐述公路路堑边坡设计国内外研究现状,找到我们亟需解决的问题,确定研究方向和思路；2、通过对山东省中部地区大量现有道路的调查,找到了以往公路建设与环境不协调的根源,揭示了现有公路路堑边坡存在的典型问题；3、系统的提出了公路路堑与地形协调的基本方法和技巧,提出了路堑边坡设计所应遵循的新理念,并针对边坡设计、截水沟设计、植被选择、景观设计及工程地质分类等方面进行了详细的描述和总结,形成了一套完整的有指导意义的边坡景观设计理论和方法；4、通过国家典型示范工程青莱高速(济青南线)的实践,证实了本文中所提出的理论和方法的实用性和可靠性,对我国半干旱地区的丘陵、山区公路建设具有一定的借鉴价值。
[Abstract]:The mileage of expressway in China ranks first in the world. The concept of expressway construction has changed from technical and economic index to safety, environmental protection, coordination, economy, comfort and people-oriented. In the new period of highway construction, highway engineering should not only meet the requirements of safety, comfort, beauty and environmental protection, but also meet the requirements of safety, comfort, beauty and environmental protection, and how to deal with the relationship between highway development and environmental harmony and the utilization of resources. Highway construction is facing an important issue. As a result of lack of supporting theory guidance, design, construction personnel are faced with a lot of difficulties. The background of highway is natural, semi-natural or artificial landscape which is full of changes. As the transition between highway subject and its background, cutting should be studied as the focus, and scientific and perfect theory should be formed to guide the design of cutting. However, very little research has been done around this work. Through the study of this subject, a reasonable solution combining cutting design with environmental coordination design is established, which embodies the stable, harmonious, natural, beautiful and economical core idea of cutting design, and provides certain support for the optimization of highway design scheme. The main contents of this paper are as follows: 1. The research status of highway cutting slope design at home and abroad is described, and the problems we need to solve are found, and the research direction and train of thought are determined. 2. Through the investigation of a large number of existing roads in the central part of Shandong Province, the root causes of the disharmony between the highway construction and the environment in the past are found, and the typical problems existing in the existing highway cutting slopes are revealed. 3. The basic methods and skills of highway cutting and terrain coordination are put forward systematically, and the new idea should be followed in the design of cutting slope, and aiming at slope design, cut-off ditch design, vegetation selection, and so on, this paper puts forward the new idea of slope design, cut-off ditch design and vegetation selection. The landscape design and engineering geology classification are described and summarized in detail, and a complete set of guiding theory and method of slope landscape design is formed. 4. Through the practice of the national typical demonstration project, Qinglai Highway (Jiqing-South Line), the practicability and reliability of the theory and method proposed in this paper are proved, and it is applied to the hilly areas of semi-arid areas in China. Mountain highway construction has certain reference value.
