The equipment of large vibration compaction was designed to do large laboratory vibration compaction test under the condition of different water content and different soil-stone proportions with sandy soil,silt soil and low liquid-limit clay.The soil pressure was collected to calculate the dynamic Poisson’s ratio,and then the deformation capability in each direction of foundation mixture in different compactness was studied.The change rule of dynamic Poisson’s ratio in soil-stone mixture was revealed.The correlation analysis model of Poisson’s ratio in soil-stone mixture was built.Sensitivity analysis on change of shear wave velocity in soil-stone mixture caused by change of dynamic Poisson’s ratio was conducted.The results showed that the dynamic Poisson’s ratio had little influence on shear wave velocity in soil-stone mixture,while the field shear wave velocity test of soil-stone foundation was done.The correlation parameters of soil-stone mixture could be calibrated and determined by Poisson’s ratio in most compact condition under fixed water content and fixed soil-stone proportion.Then the model of correlating surface wave and shear wave was built and field-verified, and a favorable effect was obtained.
