摘要
岩土体位移与岩土体力学参数间的映射关系,具有高度非线性的特点。寻求一种能精确描述这种非线性映射关系的方法,是众多研究者正在大力研究的问题。为此,采用一个多峰函数对ANN和ANFIS的拟合能力和推广预测能力进行了比较研究,结果表明,ANFIS的拟合能力和推广预测能力均优于ANN,更适合于用来建立岩土体位移与岩土体力学参数间的映射关系.
The mapping between displacements and mechanical properties of rock and soil mass is charicterized by its non-linearity. Many researchers are trying to establish an approach for describing this non-linear mapping. As a result, the authors conduct a comparision study of the fitting and generalization prediction capabilities of ANN and ANFIS using a multi-peak function. The results show that ANFIS has better fitting and generalization prediction capabilities than ANN.
