本文的目的是得到薄透水壁的多孔效应参数G。通过物理模型实验获得了不同多孔形状和孔隙率的垂直多孔薄壁的反射和透射系数。另一个实验也得到了穿孔沉箱的反射系数和总水平波载荷。介绍了波浪与这两个垂直多孔防波堤相互作用的解析解。作者和其他四位研究人员的预测与实验结果之间的反射和透射系数进行了比较。通过比较，推荐了透水板线性化阻力系数f和惯性效应系数s的估算方法。遵循Yu [1995]的公式，G的值由f和s计算。提出了一种完整的多孔效应参数G的估计方法，该方法由Yu[1995]的公式和本实验公式组成。通过将穿孔沉箱总水平波浪载荷的预测值与试验结果进行比较，验证了G的估计方法。
The present paper aims at getting the porous effect parameter G of a thin permeable wall. The reflection and transmission coefficients of a thin vertical porous wall with different porous shapes and porosities are obtained by a physical model experiment. The reflection coefficient and total horizontal wave load on a perforated caisson are also obtained by another experiment. Analytical solutions of wave interaction with these two vertical porous breakwaters are introduced. The reflection and transmission coefficients between predictions and experimental results of authors' and four other researchers' are compared. By comparisons, the estimate methods of the linearized resistance coefficient f and the inertial effect coefficient s of the permeable plate are recommended. Following the formula of Yu [1995], the values of G are calculated by f and s. A complete estimate method of porous effect parameter G is presented, which consists of the formula of Yu [1995] and the present experimental formula. The estimate method of G is validated by comparing the predicted values of the total horizontal wave loads on the perforated caisson with the experimental results.
