Abstract

Abstract

A new method to infer the probabilistic density functions of geotechnical parameter is presented. Based on numerical approximation theory, the Legendre polynomial is introduced to match the probabilistic density function of geotechnical random parameters. Kolmogorov-Smirnoy test is used to verify this method.
