     The sensitivity of multiple modes Rayleigh waves phase velocity are analyzed based on a low-velocity interlayer model.The results show that the wave phase velocity of multiple modes is very sensitive to the shear velocity of low-velocity interlayer and thickness of the layer.The wave phase velocity is more sensitive to the shear velocity than thickness of the layer.The sensitive band of fundamental model is concentrated in a narrow band of low frequency.Inverting Rayleigh waves of fundamental and higher modes can effectively improve the accuracy of inverted S-wave velocities.The sensitivity of multiple modes Rayleigh waves phase velocity to the shear velocity of low-velocity interlayer and thickness of the layer show that Rayleigh surface wave method is suitable for low-velocity interlayer survey.
