基于未确知-集对耦合的生态护坡工程质量评价体系及应用
|
摘要
[目的]建立一个科学合理的生态护坡工程质量评价体系对生态护坡工程的质量等级进行评价,为边坡生态恢复方案的选用提供理论依据。[方法]结合系统工程学理论,将生态护坡工程视为"边坡—基质—植物群落"的复合系统加以评价研究。考虑到生态护坡工程质量评价过程中信息的不确定性、未确知性,建立一种新的未确知测度与集对分析耦合的评价模型。运用未确知测度理论,计算出各生态护坡方案的多指标综合测度评价向量,将生态护坡系统中的不确定性信息转化为相对确知的信息;基于集对分析理论,引入可以体现生态护坡系统确定性与不确定性的同异反联系度,进一步提高了评价精度。最后,将该模型运用于某地区铁路边坡生态恢复工程中的3种备选方案进行评价。[结果] 3种备选方案的质量等级皆为Ⅱ级,其联系数分别为0.384,0.386和0.539,第3种方案(TBSⅡ护坡工程区)最优。[结论]优选结果与灰色评价模型的计算结果几乎一致且更符合工程实践结果,是一种有效地针对生态护坡效果研究的新方法。
[Objective] A suitable quality evaluation system for ecological slope protection was established to evaluate the quality grade of ecological slope protection project, and to provide a theoretical basis for selecting the slope ecological restoration method. [Methods] In combination with the system engineering theory, the ecological slope protection engineering is regarded as a complex system of "slope-matrix-plant community". A new evaluation model of unascertainty measure and set pair analysis were established to be used in the process of ecological slope protection project quality evaluation. Using unascertained measure theory, the multi-index comprehensive measure evaluation vector of each ecological slope protection scheme was calculated, and the uncertainty information in the ecological slope protection system was transformed into relatively unascertained information. The pair analysis reflects the degree of similarity, difference and inverse relation between the certainty and uncertainty of ecological slope protection system, and further improve the accuracy of evaluation. Finally, the model was applied to evaluate three alternative schemes of railway slope ecological restoration project. [Results] The quality standard of the three kinds of schemes are all level Ⅱ. The correlation numbers index were : 0.384, 0.386 and 0.539, respectively. The results showed the third option(TBS Ⅱ slope protection) was the best. [Conclusion] The result of optimization was almost consistent with the calculation result of grey evaluation model and reflected the result of engineering practice well. We concluded that the method adopted in this paper is an effective new method to study the effect of ecological slope protection.
