摘要

山区公路边坡量多面广、面临地质环境复杂以及形成时间短等特点使得目前对其安全稳定性评价问题仍没有得到有效解决，边坡安全稳定问题制约和阻碍了我国山区公路尤其是高等级公路的进一步发展。基于简单关联函数对各评价指标进行相对重要程度排序，采用层次分析法和专家效度对评价指标权重进行修正，利用物元可拓分析方法建立山区公路高切坡物元可拓评价模型，对重庆市两巫（巫山－巫溪）公路K88＋680段高切坡进行综合评价，研究结果表明该高切坡安全评价等级为Ⅲ级，整体欠安全，开挖后需要采取相应防护措施。

Abstract

Slope safety stability is the bottleneck problem for the development of mountainous highway

especially high class highway in China

which results from greatness slopes along highway in mountainous area

complex geological environment and short forming age. The important degree arrangement of various indexes was carried out based on simple dependent function. And weighting system of indexes was modified with analytic hierarchy process and expert reliability. With indexes and weighting system

matter element extension model for highcutting slope along highway in mountainous area was proposed by matterelement extension method. A case study was undertaken for K88+680 highcutting slopes along WushanWuxi road in Chongqing city based on the model. It was indicated that the safety grade is Ⅲ and the slope is instable.
