【摘要】 本文对模糊单元及其应用进行了比较详细的讨论。建立了模糊超参单元,推导了模糊单元和有限元耦合模拟无限系统的全部计算公式;对平面和空间弹性地基、在自重和水压作用下的重力坝地基等无限介质问题,进行了具体的分析计算;讨论了各种隶属函数对解的影响 ;与普通有限元和无限元进行了分析对比,对模糊单元的特点和优点进行了评价。更多还原

【Abstract】 In this paper a comparatively detailed discussion about fuzzy element and its application is given,the fuzzy superparametric element is set up and all the fo- rmulas which fuzzy element couple in finite element to simulate infinite ststems are described.Also concrete analysis and computation about infinite medium prob- lem such as the planar and elastic foundation,the gravity dam foundation subjec- ted to sole weight and water pressure is made.research on the effect of various membership function to the solution is done.Results show that this analytical model is characterized by high accuracy and significant economy.更多还原
