The thickness of the ice cover on the wall surface heat transfer is greater than the thickness of it on the air heat transfer form. The thickness of the ice cover on the wall surface heat transfer along the way changes slowly, but it on the air heat transfer along the way changes significantly. Reducing the entrance velocity, lowering the wall surface or air temperature, the formation of the thickness of the ice cover will increase; in the 3D circumstances, The thickness of the ice cover was relatively uniform in the import of the U-turn model, the ice cover was gradual accumulation in the convex bank when the stream traversed the import of the U-turn model, the thickness of the ice cover in the convex bank was significantly bigger than the thickness in the concave bank. The temperature field under the ice cover tends to be complex because of the existence of the secondary flows. The temperature in the convex bank is greater than it in the concave bank. Compared with the data from experiments, the laws in the numerical simulation are similar with them in the experiments

模拟结果显示：二维情况下，运用壁面传热形成的冰盖厚度大于运用空气传热形成的冰盖厚度，壁面传热形成的冰盖厚度沿程变化缓慢，而空气传热形成的冰盖厚度沿程变化明显，减小入口流速，降低壁面或空气温度等，形成冰盖的厚度都会增大；三维情况下，弯道入口处凸、凹岸形成的冰盖厚度基本相同，进入弯道后，凸岸形成的冰盖厚度逐渐增大，而凹岸的冰盖厚度逐渐减小，受横向环流的影响，冰盖下水流的温度场趋向复杂，并且凸岸的温度小于凹岸的温度；与实验室实验所得数据相比较，数值模拟研究得到的规律基本符合实验规律。

目前我国东部的石油勘探工作已进入精细勘探阶段，如何确定陆相地层中薄储层的空间展布规律及其性质已成为一个亟待解决的问题，由于我国东部的绝大多数中、新生代陆相含油盆地大都以薄层砂、泥岩沉积为主，夹有少量薄层碳酸盐岩、页岩及膏盐层，地层岩性和厚度横向变化均较大，而且这些地层的厚度远远低于常规地震勘探的垂向分辨率，因此，从理论上研究沙泥岩薄互层地震反射特征、薄互层组内的单层厚度、子结构厚度、互层组内层数、入射子波类型、主频、采样率等各种因素对反射波特征的影响，将对我们定性或定量求取薄互层组中各单层厚度或薄层组的厚度、预测薄储层的空间展布规律有一定的理论和现实意义。
