本文提出了基于模型试验所测得的波压力资料,进行防浪胸墙断面的优化设计方法。在已给的设计波要素、墙高和堤前相对水深等参数下,由模型试验实测波压力值,以抗滑、抗倾、地基应力和几何等约束为条件,以胸墙底宽和直立部分底宽为设计变量,以墙重为目标函数,用电算求解最轻墙重和相应的设计变量值。文中,还结合某港防浪墙的具体例子,指出了本文提出的优化设计法比传统的安全校核法的优越性。
In this paper, the optimal design method of wave-resistant chest wall section is proposed based on the wave pressure data measured by the model test. Under the given parameters of design wave, wall height and relative water depth before embankment, the wave pressure measured by the model test is based on the constraints of anti-skidding, anti-tilting, foundation stress and geometry, The bottom width is the design variable, the wall weight is the objective function, and the longest wall weight and the corresponding design variable value are calculated by using the computer. In the article, the author also points out the superiority of the optimization design method proposed in this paper over the traditional safety verification method, combining with the concrete example of a port wave prevention wall.
