Correlation Between Shear Wave Velocity and Burial Depth of Conventional Soil in Kunming Basin
摘要
Abstract
Based on the shear wave velocity data of site boreholes in the seismic safety evaluation of Kunming Basin,the correlation between shear wave velocity and burial depth of six kinds of conventional soil in Kunming Basin was discussed by the least square method and nonlinear regression method.The statistical empirical formulas for the linear model,power function model,quadratic polynomial model,and complex function model of shear wave velocity and burial depth of conventional soil were recommended.Finally,the above-recommended models were tested by the measured values of borehole shear wave velocity of new projects.The results show that there is a strong correlation between shear wave velocity and burial depth of conventional soil in Kunming Basin,and the degree of sample dispersion increases with the increase in burial depth.The fitting values of each model in this paper are very close to the measured values,and the error percentage is very low.The model is reasonable and reliable.The research results can provide a reference for the related work of borehole shear wave velocity in Kunming Basin.关键词
