对分层流中海底边界混合层发展问题提出了一个新的垂直积分模型。在这个模型里，新建立的能量方程中出现了一个表征速度大小随高度变化规律的参数，从而得出了被Ｐｏｌｌａｒｄ等人文章中应用的但被本文修正过的Ｒｉｃｈａｎｄｓｏｎ数封闭模型，对在水平乎底上的混合层成长问题，给出了分析解。从而把以往的公式都统一到本文的结果中，而且给出了以往海底边界混合层公式的理论依据与适用范围，这个结果与Ｗｅａｔｈｅｒｌｙ与Ｍａｒｔｉｎ（１９７８）用Ｍｅｌｌｏｒ与Ｙａｍａｄａ（１９７４）的高阶模型所得的数值解结果是基本一致的，并与现场实验相符。
A new vertical integral model is proposed for the development of mixed horizon in the stratified flow. In this model, a parameter that characterizes the velocity variation with height appears in the newly established energy equation, which leads to the Richardson number closed model applied by Pollard et al. But modified by this paper, At the bottom of the mixed layer growth problems, given analytical solution. The results are consistent with the previous ones. The theoretical basis and application range of the mixed layer formula of the seabed boundary are given. This result is similar to that of Weatherley and Martin (1978) using the high-order models of Mellor and Yamada (1974) The results of the numerical solution are basically consistent and consistent with the field experiments.
