The current researches on pavement mechanics usually focus on the derivation of analytical solutions and the exploration of the factors affecting them, there are few studies on the difference of analytical solutions. In order to solve this problem, transfer matrix method, stiffness matrix method, wave transfer method and reflection and transmission matrix method were applied in the deduction process of the analytical solutions considering the transverse isotropy of materials and the contact state between layers. On this basis, the calculation efficiency and the range of adaptability of the above four analytical solutions are studied by combining four kinds of pavement structures. The results show that: ①for the matrix scale, reflection and transmission matrix method, transfer matrix method, stiffness matrix method and wave transfer method increase in turn; ② for the solution speed, the transfer matrix method takes much less time than the other three methods, while the reflection and transmission matrix method consumes the most time; ③in the numerical stability, the transfer matrix method is very easy to overflow data when calculating the dynamic response of finite thickness, while the other analytical solution methods have good numerical stability; ④in practical application, the transfer matrix method is particularly suitable for the surface of semi space problems, and the stiffness matrix method can only calculate the dynamic response of the surface of each structural layer, however, the wave transfer method and the reflection and transmission matrix method can solve the dynamic response of any position in the pavement.
