| 摘 要： | 目的]研究高速公路施工过程对沿线山体植被、水土保持方面的影响,为路段后期水土保持工作采取最优的防护措施提供参考依据。方法]基于高速公路施工期水土流失影响因素的分析基础,建立多层次、多指标的高速公路施工期水土流失评价体系。通过现场工程参数分析,将水土流失影响指数(SWⅡ)引入同一高速公路不同路段水土流失影响的评价中。选用基于客观赋权法的熵值法确定评价体系中各评价指标对水土流失的影响程度。依托在建梁平至忠县高速公路项目,针对初步选定的9段路段进行施工期水土流失评价。结果]确定研究区水土流失情况严重的4段重点路域,并将其划定为水土流失重点防护区域。结论]验证了多层次、多指标的高速公路施工期水土流失影响评价体系的合理性,排除了人为因素的干扰,可以更加客观、科学地确定高速公路施工期水土流失重点路域。

| Abstract: | Objective] Considering the disturbance to environment caused by highway construction in order to found the optimal protection measures of soil and water loss caused by highway construction was demonstrated.Methods] Based on the comprehensive analysis of factors affecting soil erosion during the construction,a multi-level and multi-index highway construction evaluation system with respect to soil and water loss was established.Via engineering parameter analysis,a parameter,termed as SW Ⅱ,was introduced into the evaluation of different sections of highway.The entropy method was chosen to determine the influence degree of each evaluation index of the evaluation system.9 preliminary sections of liangping-zhongxian highway project were chosen to evaluate.Results] 4 sections were classified as severe loss level and as key protection areas.Conclusion] This article verified the rationality of the evaluation system and eliminated manmade interference.This evaluation system can determine key areas of soil and water loss under highway construction in a more objective and scientific way. |
