英文摘要：

Based on the parametric modeling capabilities of GOCAD, this paper gets the data of the shear wavevelocity and the longitudinal wave velocity which were measured by acoustic test method on each stratum alongthe subway in Chengdu . They were used as the regionalized random variables to build attributive geologic model.The established 3D geological model can not only reflect the characteristics of stratum spatial distribution but alsointuitively show the dynamic elastic mechanics characteristics of geologic body. It achieved combination and visu-alization of the distribution of spatial structure and mechanical properties. In addition, the use of kinds of geolog-ical statistical analysis methods provided by GOCAD software canpredict any parameter values of arbitrary pointin the model and well observe the change trend of acoustic parameters in the study area, which can be simple andefficient to evaluate the soil type and site level along the subway, assisting designers in achieving intuitive andaccurate engineering geological information conveniently.
