从可拓理论在工程地质领域应用出发,首先分析了工程地质领域问题的特点——“等级对关联度的影响效果相同,但等级的取值区间长度可以不同;等级内关联值随取值呈一阶线性变化”;其次根据一个应用可拓理论中物元模型进行工程地质建模的简单特例,将物元模型展开,绘制出关于所有等级的“关联度-等级(影响因素值)”关系曲线,根据曲线与实际现象的不符之处分析模型存在的问题;提出一个新的关联函数计算方程,改进了原关联函数方程与实际的不符之处;最后通过分析改进后的方程曲线,论证改进后方程较符合工程地质领域问题的实际情况。总之,本文分析了可拓理论中的物元模型在工程地质领域中应用存在的问题,改进了物元模型中的关联度计算函数,对可拓模型在工程地质领域中的广泛和正确应用起到了推动作用。
Based on the application of extenics theory in the field of engineering geology, the characteristics of the problems in engineering geology are analyzed first - the effect of the grade on the degree of association is the same, but the length of the grade interval can be different; First-order linear change “. Secondly, according to a simple and special case of engineering geology modeling using matter-element model in extension theory, the matter-element model is expanded to draw” Relevance-Rank ) Curve, demonstrate that the improved equation is more in line with the actual situation in the field of engineering geology. In summary, this paper analyzes the problems existing in the application of the matter-element model in extension theory in the field of engineering geology, and improves the calculation function of the degree of relevance in the matter-element model. Since the extensive and correct application of the extension model in the field of engineering geology To promote the role.
