并在此基础上分析了冻结速率和冻胀率之间的关系，得出了土体的冻胀率随冻结速率增大呈幂指数形式递减。

The results show that whether the stiffness profiles are smoothly varying or layered, the fundamental mode dominates the surface wave field and the effective phase velocity approaches to the phase velocity of the mode in far field for the regular profiles. For the irregular profiles, the higher modes have a significant influence on the surface wave field. The intensity and the frequency range of the influence are related to variation of the profile stiffness.
