Research on spatial simulation method of soil equivalent shear wave velocity

It expatiates the physical significance of double parameters in dividing building place classification,commentates present problems in dividing building place classification,indicates that soil layer equivalent cutting wave speed can not be used to divide the style of place soil,also can not use soil layer equivalent cutting wave speed value to average place.

Based on the characteristics of the pseudo-dynamic testing and taking into account the permissible system accuracy, this paper introduces the concept of equivalent shear stiffness, and proposes the high order single-step algorithm of pse.

Utilization of shear wave velocity in assessment of liquefaction potential of saturated sand under level ground during earthquakes;

Shear velocity is an important parameter in evaluating the dynamic properties of a site In this paper,the statistical relation of shear velocity with soil properties is obtained by statistical analysis of the values tested in Tianjin and Shanghai The obtained formula is of some referential value for the evaluation and classification of a site in the coastal and offshore areas of our countr

Summary on the study of liquefaction evaluation by shear-wave velocity;

Application of multiple cross-correlation functions to the measurement of shear-wave velocity

Through comparison measurement and analyses of shear-wave velocity in subsoil of Huaiyin Institute of Technology main-building before piling and after,the author discovers the site classification may be changed by piling.
