发布时间：2018-08-11 18:06
【摘要】：目前而言,国内外对道路线形评价的研究已进行得比较深入,相关的评价理论与评价方法灵活多样。但是截止到目前为止,对于道路线形质量优劣评价较成熟的研究大部分是从线形质量的某一个方面进行相关的分析研究及评价。另外就是在道路线形质量综合评价时评价指标体系的建立不够完善,最后由于线性评价具有不确定性与确定性的双重性质,所以即便是建立起综合评价模型,但是由于对这二者的处理不够理想造成数据的损失。通过采用理论研究与实际工作相结合的研究方式,使得我们对道路线形设计评价问题有一个新的认识,不断优化和提高道路线形设计评价的水平。研究成果在理论方面,将推动道路线形设计评价的理论研究,同时丰富优化道路线形设计评价领域的应用;在现实方面,可帮助设计、管理部门改善其做出的决策,提高方案的合理性和有效性,扩大决策范围。主要的工作内容包括以下几点:首先在借鉴前人研究成果的基础之上构建出科学、合理、全面的道路线形设计评价指标体系,并对相关评价指标值进行归一化处理。其次在分析优化模糊软集合特性的基础上,构建出基于模糊软集合的路线设计质量评价模型。最后为验证提出的评价模型,采用永川双石至江津塘河段高速公路及重庆绕城高速公路为应用实例进行道路线形评价,取得的具体研究成果如下所示。对于道路线形设计综合评价的研究,将其重新划分为建设者、使用者、环境观点三个大方面,站在新的角度观点综合考虑问题,使得评价指标的选取更加全面合理。从建设者这一新的角度出发,详细论述道路建设者在道路线形设计综合评价中的作用,归纳总结出了建设者参与评价的新指标包括。基于使用者的观点从而研究提炼出相关的设计评价指标,并采用定量及定性分析相结合,参数评价与经验判断相结合的两大方式,即定量指标和定性指标。通过对环境影响的因素进行详细的分析,从而归纳出对环境影响的主要评价指标并提出了新的评价指标作为线形评价指标体系的一部分,即环境影响指标。将模糊软集合这一新的概念引入道路工程领域,在模糊软集合的理论基础之上,建立起了基于模糊软集合的路线设计质量评价模型,该模型可以合理地处理信息的确定性与不确定性,将两种信息进行融合保证了信息的完整性,使评价结果更加符合道路线形质量的实际情况。最后通过项目的验证表明该评价模型是合理可行的。
[Abstract]:At present, the research on road alignment evaluation has been carried out deeply at home and abroad, and the relevant evaluation theory and evaluation methods are flexible and diverse. However, up to now, most of the studies on the evaluation of road alignment quality are related to the analysis and evaluation from a certain aspect of the linear quality. In addition, the establishment of evaluation index system is not perfect in the comprehensive evaluation of road linear quality. Finally, because the linear evaluation has the dual nature of uncertainty and certainty, so even the comprehensive evaluation model is established. However, data loss is caused by the inadequate treatment of the two. Through the combination of theoretical research and practical work, we have a new understanding of road alignment design evaluation, and constantly optimize and improve the level of road alignment design evaluation. In theory, the research results will promote the theoretical research of road alignment design evaluation, and enrich the application in the field of optimizing road alignment design evaluation. In reality, it can help design and management to improve their decision-making. Improve the rationality and effectiveness of the program, expand the scope of decision-making. The main work includes the following points: firstly, a scientific, reasonable and comprehensive evaluation index system of road alignment design is constructed based on the previous research results, and the relevant evaluation index values are normalized. Secondly, the quality evaluation model of route design based on fuzzy soft set is constructed on the basis of analyzing the characteristics of optimized fuzzy soft set. Finally, in order to verify the proposed evaluation model, the highway from Yongchuan Shuangshi to Jiang Jin Tanghe and Chongqing around the city expressway are used to evaluate the road alignment, and the concrete research results are as follows. The comprehensive evaluation of road alignment design is reclassified into three aspects: constructor, user and environmental viewpoint. From a new point of view, the comprehensive evaluation is considered, which makes the selection of evaluation index more comprehensive and reasonable. Starting from the new angle of constructor, this paper discusses in detail the role of road builders in the comprehensive evaluation of road alignment design, and summarizes the new indicators of constructors' participation in evaluation. Based on the user's point of view, the relevant design evaluation indexes are studied and refined, and the quantitative and qualitative analysis, parameter evaluation and empirical judgment are used to combine the quantitative index and the qualitative index. Through the detailed analysis of the factors of environmental impact, the main evaluation indexes of environmental impact are concluded and a new evaluation index is proposed as part of the linear evaluation index system, that is, the environmental impact index. The new concept of fuzzy soft set is introduced into the field of road engineering. Based on the theory of fuzzy soft set, the quality evaluation model of route design based on fuzzy soft set is established. The model can deal with the certainty and uncertainty of the information reasonably. The fusion of the two kinds of information ensures the integrity of the information and makes the evaluation results more in line with the actual situation of road alignment quality. Finally, the project verification shows that the evaluation model is reasonable and feasible.
