材料性能的随机场特性参数的检定方法

Determination of Parameters of Random FieidProperty of Materials

摘要: 本文建议根据相关函数分析结果描述材料随机场性质，提出用曲线拟合方法检定随机场特性的分析模型参数。经过实例分析，指出指数余弦式模型的现实性及特点。

Abstract: correlation function is suggested to discribe the ramdom field property of soil layer or con- crete block. Curve-fitting procedure is used to determine the parameters of the analytical model.Reality of cosine-exponential correlation function is illustrated by examples.
