Abstract:: Using the shear wave velocity from the borehole data from the Report of Chengdu Seismic Safety Evaluation,we qualitatively study the relationship between the shear wave velocity and soil depth of ten common types of the soil in Chengdu region.Then,taking the goodness of fit as a comprehensive evaluation index,we set up fitting function models corresponding to various types of soil layers.Using the borehole data from a drainage project of a tunnel in Chengdu,we compared the shear wave velocty evaluated by the mathematical model we set up,and the shear wave velocity evaluated by GA-BP model,and the ones by other models.We find that the shear wave velocity is related with the soil depth,and the dispersion increases when the depth increases.The model recommended in this paper has higher appraisal precision.
