- 摘要:
- 为评价山区公路沿线高陡边坡稳定性，保障道路行车安全，基于代数表示的粗糙集理论和条件信息熵表示的粗糙集理论，结合理想解的思想重新定义各属性重要度的确定方式，提出新的适用于山区高陡边坡的权重确定方法，并建立高陡边坡稳定性评价体系，基于模糊理论以某高速公路高陡边坡工程为研究背景，建立山区高陡边坡模糊稳定性评价模型，对边坡稳定性进行评价。研究结果表明：隶属度最大值为0.397，对应边坡稳定状态为“极不稳定”，与实际情况基本一致，验证该权重方法客观、准确，为更好评判山区公路沿线高陡边坡稳定性提出新的方法。
- Abstract:
- In order to evaluate the stability of high and steep slopes along the mountain highway more accurately,and ensure the road traffic safety,based on the rough set theory represented by algebra and the rough set theory represented by the entropy of conditional information and using their advantages in treating the randomness and incompleteness,the determination methods of the importance of each attribute were redefined combining with the idea of ideal solution.A new method of weight determination applicable to the high and steep slopes in mountainous areas was put forward,and an evaluation system of the stability of high and steep slope was established.Taking the high and steep slope project of a certain expressway as the research background,a fuzzy stability evaluation model of the high and steep slopes in mountainous areas was established based on fuzzy theory,and the stability of slope was evaluated.The results showed that the maximum membership was 0.397,and the corresponding slope stability was “extremely unstable”,which was basically in line with the actual situation and indicated that the weighting method was objective and accurate and the evaluation model was scientific and reasonable.It provides a new method for better judging the stability of high and steep slopes along the mountain highway.
