Seismic Mechanics and Engineering Application Analysis of Shear Wave Velocity Inferring

Abstract:

The soil shear wave velocity is the key parameter in site seismic response analysis. And it is also one of the important parameters in evaluation of seismic safety for engineering sites or the seismic microzonation. Normally, the parameter is obtained through the field testing. Sometimes shear wave velocity testing could not arrive at technical requirement or the technical requirements due to the actual condition. Then it is necessary to develop the parameter inferring method. In this paper, the data of shear wave velocity of soils at 46 typical boreholes in Dongying are selected for regressive statistic analysis. Based on the data, the formulas of shear wave velocity with linear function and power function are obtained. Considering the influence of the soil classification to the soil shear wave velocity, the new inferring formulas are obtained. Then the inferring formulas of the shear wave velocity are applied at 4 boreholes in one residential building. It is shown that the calculation results conform well with the site testing results, and the formulas are applicable for engineering with sufficient accuracy.
