本文采用有限元法计算分析研究了防波海堤护坡块体的稳定性,结合我国东南沿海的海堤结构型式对设计高潮位波浪作用下的堤内流场分布作了计算,并分析求得护坡块体的局部稳定性计算公式,然后引用波浪水槽试验资料加以验证,并与习用的Hudson公式作了对比评述

The stability of slope protective blocks on the breakwater is investigated through the calculation and analysis of a finite element method.Combining with the types of the breakwater structure along the coast of southeast,this paper shows the calculations of the current field distribution within the range of the breakwater under the action of waves at design high tide level and gives a formula to calculate a partial stability of slope protective blocks.To verify the formula,wave flume test data were adopted thereby and the comparison with the traditional Hudson formula was conducted.
