设计直立式堤头时要不要比堤身加宽,长期以来是有争论的,它涉及堤头稳定作用的外力如何考虑。解放以来,由于我们一直沿用苏联五十年代的计算方法,即堤头外侧按设计波高(H)作用下的波峰压力,内侧按设计波高的二分之一(H/2)作用下的波谷吸力组合起来进行稳定验算,国内不少工程是采用这种方法进行设计的。此外,有的
It is controversial for a long time whether to design a vertical dike or not to be wider than a dike, and how it considers the external forces that affect the stability of the dike. Since liberation, we have used the calculation method of the 1950s, that is, the crest pressure on the outer side of the dyke at the design wave height (H) and the trough suction on the medial side at half the designed wave height (H / 2) Combination of stable checking, many domestic projects are designed using this method. In addition, some
