摘要
基于层次分析原理,综合考虑护坡功能、生态效益、安全要求,提出边坡生态防护工程在工程质量评定、养护管理不同阶段的评价指标体系并确定各指标权重。建立两阶段、三准则、九指标的生态防护效果评价方法,对铁路路基边坡生态防护效果进行全面评价。坡面植物覆盖率、成活率及根系发育情况对铁路路基边坡生态防护效果评价的影响较大。该方法应用于京雄城际铁路固安东站路基边坡生态防护效果评价,证明了其可行性。
Based on the principle of analytic hierarchy process,with the comprehensively consideration of the slope protection function,ecological benefits and safety requirements,the evaluation index system of slope ecological protection engineering in different stages of project quality evaluation and maintenance management was proposed,and the weight of each index was determined.That was to establish the evaluation method of ecological protection effect of two stages,three criteria and nine indicators,which could comprehensively evaluate the ecological protection effect of railway subgrade slope.The vegetation coverage rate,survival rate and root development of slope had a great impact on the evaluation of ecological protection effect of railway subgrade slope.The method was applied to the evaluation of subgrade slope ecological protection effect of Gu’an East station of Beijing-Xiongan intercity railway,and its feasibility was proved.
