Based on the hydrodynamic model test,the relationship of relative hydrodynamic coefficient and K C is analyzed by introducing the relative trench shape coefficient α r ; there is a good relation in the shallow trench. According to α r of the shape of designed trench and pre chosen K C, the reduction coefficients and sheltering effect can be decided by the result in this paper.

基于水力模型实验,引入相对沟形系数αr,获得了以αr为表征的相对水动力系数与KC数的关系;对于浅沟而言,这种关系较有规律性。根据所设计沟形的αr值和所选定的KC值,应用本文结果,可以方便地判断其力折减程度和掩护效果
