首先分析了流场和沙流场的本构方程，然后在考虑十字路口、改变路面高度和气流流场的情况下建立了不同的沙漠公路数值模型，然后建立了具有不同复杂气流场的3种不同模型，用于模拟空气流场和沙流场弱耦合作用下的沙纹形成过程。最后对这些模型进行了数值模拟，讨论了复杂气流场对砂土形态的影响过程。结果表明：在均匀气流场作用下，在十字路口中部区域形成了直线平行纹波和喇叭纹波，且当道路高度高于沙面高度时，沙漠公路上纹波的波长大于道路周围纹波的波长；在非均匀复杂气流场下，会形成复杂的弯曲波纹，而在旋风出口的局部区域，则不会形成波纹。
The flow field and the sand flow field constitutive equations are analyzed at first, then the different desert highway numerical models are established by considering the crossroad and by changing the road surface height and air stream flow field, then three kinds of different models with different complex air flow fields are made for simulating the sand ripple formation process by weak coupling of air and sand flow field, and finally the numerical simulations of these models are conducted and the affect process of sand morphology under complex air flow fields are discussed. The results show that under the uniform airflow field, the straight parallel ripple formed and the flared ripple formed in the middle region of the crossroad, and the wavelength of the ripples on the desert highway is bigger than that of the ripples around the road when the road height is higher than that of the sand surface height. Under the nonuniform complex airflow field, the complex curved ripples are formed, and some of the local area, where the whirlwind exits, no ripples are formed.
