粘结护岸的孔隙度和粗糙度对护岸及其基础的水力性能和波浪荷载至关重要，从而影响整个结构的稳定性和耐久性。在汉诺威大波浪水槽（GWK）进行的两个大型试验系列的初步比较分析结果简要地表明了这一点，两个显著不同的护岸：高多孔性和粗糙的聚氨酯粘合骨料（PBA）护岸和几乎不透水且相对光滑的互锁模式放置块（IPPB）护岸。这些结果激发了为期三年的研究项目BoPoRe（粘合多孔护坡）的启动，该项目的主要目标是更系统地、单独地研究不同坡度下孔隙度和粗糙度的相对重要性。简要介绍了该工程，并简要讨论了在大范围波浪条件（冲浪相似参数0.93-7.21）下，采用9种配置对护岸的孔隙度和粗糙度进行初步比例模型试验的初步结果。
The porosity and roughness of bonded revetments are both crucial for the hydraulic performance and the wave loading of the revetment and its foundation, and thus for the stability and durability of the entire structure. This is briefly shown by the selected results of a tentative comparative analysis of two large-scale test series performed in the Large Wave Flume (GWK) Hanover with two significantly different revetments: a highly porous and rough polyurethane bonded aggregate (PBA) revetment and an almost impermeable and relatively smooth interlocked pattern placed block (IPPB) revetment. These results motivated the initiation of the three years research project BoPoRe (Bonded Porous Revetments) which has the primary objective to investigate more systematically and separately the relative importance of both porosity and roughness for different slope steepnesses. This project is briefly introduced and the first results of preliminary scale model tests using 9 configurations for the porosity and roughness of the revetment subject to a wide range of wave conditions (surf similarity parameters 0.93-7.21) are briefly discussed.
