随着我国高速公路的大量修建,软土问题变得越来越突出,已成为影响道路工程质量、进度和造价的关键因素之一.因此,加强对软基处理方案决策方面的研究对我国交通事业的发展具有相当重要的现实意义.针对软基处理方案影响因素的不完整性和不确定性,提出基于多层次模糊理论的高速公路软基处理方案决策模型,在该模型中,建立了多层次递阶模型,利用层次分析法确定了各影响因素的权重,最后确定了各方案的整体排序.实例研究结果表明:该模型合理有效、简单实用.
With the massive construction of expressway in our country, the problem of soft soil becomes more and more prominent, which has become one of the key factors affecting the quality, progress and cost of road engineering.Therefore, the research on the decision- The development of the enterprise has a very important practical significance.According to the incompleteness and uncertainty of the influencing factors of the soft foundation treatment scheme, a decision model of soft ground treatment scheme based on the multi-level fuzzy theory is proposed, in which more Hierarchical hierarchy model, the use of analytic hierarchy process to determine the weight of the various factors, and finally determine the overall ranking of each program.Example results show that: The model is reasonable and effective, simple and practical.
