一类生态护坡冲突问题求解的可拓知识挖掘方法

A Method for Solving Conflict Problem of Ecological Slope Protection Based on Extension Knowledge Mining

为研究公路边坡中坡面不具备种植条件时生态护坡策略的形成方法,将边坡工程学与可拓学结合起来,通过对工程实例的研究总结,提出了基于可拓知识挖掘的公路生态护坡策略形成方法,该方法的一般运用流程是:①用基元的形式表达生态护坡的具体目标;②挖掘目标基元的相关型知识,以相关网的形式表达出来;③挖掘相关网中的基元的发散型知识,以发散树的形式表达出来;④结合专业知识,从上述发散型知识中,寻找能解决问题的基元或基元的组合,形成潜在的生态护坡方案;⑤通过技术经济比较,从潜在方案中选取较优方案.工程实例分析表明,该方法是可行的,有利于摆脱边坡设计中对设计者经验、灵感等个体能力的过度依赖,具有重要的边坡工程应用价值.

In order to research the formation method of ecological protection strategies of highway slope when the slope does not have planting conditions,Slope Engineering has been combined with Extenics in this paper,and the formation method of ecological slope protection strategy based on extension knowledge mining been put forward through the research and summary of project cases.The general application process of this method is as follows:①Express the specific goal of ecological slope protection in the form of basic-element.②Mine the correlated knowledge about basic-element of the goal,and express this knowledge in the form of correlation network.③Mine the divergent knowledge of the basic-elements in the correlation network,and express it in the form of divergent tree.④Combined with professional knowledge,we can find the basic-element or combination of basic-elements that can solve the problem from the above divergent knowledge,and form the potential ecological slope protection strategies.⑤Select better scheme from the potential schemes through the comparison of technology and economy.The analysis of project cases shows that the method is feasible,which is helpful to get rid of the excessive dependence on the designer's experience,inspiration and other individual abilities in slope design,and has important practical value in slope engineering.
