摘要
研究目的:在山区综合考虑生态环境因素选择边坡坡度,以减小山区公路建设对生态环境的影响。研究结论:在人们越来越重视生存环境的今天,如何合理选取边坡坡度才能对生态环境的影响最小成为一个重要的课题。本文根据影响边坡确定的众多因素,利用主客观评价方法,综合边坡稳定性、工程经济、生态环境因素,提出确定边坡坡度的评价指标以及综合评价模型。在此基础上,本文应用主客观评价方法,综合经济、社会和环境等因素,确定山区合理的边坡坡度。工程实践表明,用本文方法确定的山区边坡坡度是合理的,能减小公路建设对生态环境的影响。
Research purposes: The degree of side slope of mountainous highway should be chosen with consideration of the local ecological environment for the purpose of reducing the influence of highway construction on the local ecological environment.
Research conclusions: How to choose slope degree becomes a hot study issues at present. With considerations of many factors of deciding the slope degree, slope stability, construction cost and ecological environment, the slope evaluation index and model for the slope degree are presented by adopting subject and object evaluation method. The engineering practice indicates the slope degree decided with this method is reasonable, which can reduce the influence on environment effectively.
