HETEROGENEITY OF ROCKS AND SOILS AND ESTIMATIONS OF ROCK MECHANICS PARAMETERSBY CONDITIONAL SIMULATION
岩土体的非均质性及力学参数的条件模拟赋值

The mechanics parameters of engineering rocks and soils usually are of the property of spatial and random variations due to the heterogeneity and should be considered as the spatial random fields. The reseaare made on both the spatial variation analysis of the random fields and the estimations of rock mechanicparameters in elements of FEM by conditional simulation. The advantages of this estimation method are not only that the double characteristics of spatial variations of the random fields are considered,but also that the true dispersions of the random fields could be realized better in the value estimation of the rock mechanics parameters in elements compared with the Kriging method.
