摘要:
结合长三角地区内河限制性航道的特点,通过优化航道护岸硬质结构的竖向尺度及纵向布置,提出了箱体与插板组合型生态护岸结构.依托航道整治工程进行现场试验,定量分析了该生态护岸结构的船行波反射系数、二级坡脚处波高等.现场试验结果表明:该生态护岸在中高水位时的船行波反射系数与船行波最大波高显著相关,船行波最大波高介于8~77 cm时,反射系数为0.82~0.50,波高越大,反射系数越小;一般情况下二级生态护坡坡脚的波高较小,平台上种植的水生防浪植物成活后,能够起到防护船行波的破坏作用.与连续箱体护岸相比,该生态护岸在增强结构消浪效果的同时,亦能取得较好的经济效益.
Abstract:
According to the characteristics of inland restricted navigation channel in the Yangtze River Delta, a new ecological revetment using boxes and flappers was proposed by optimizing the vertical size and the longitudinal arrangement of the rigid structure of the traditional revetment. Its dissipation of ship-generated waves was measured by the reflection coefficient of the ecological structure and the wave height at the toe of the upper slope based on the field trial in a waterway regulation engineering. The trial results show that the reflection coefficient is significantly correlated with the maximum height of the ship-generated wave at the mean and high water levels. The values of the reflection coefficients are 0.82 to 0.50 when the maximum wave heights range from 0.08 m to 0.77 m. The larger the wave height, the smaller the reflection coefficient. The wave height is relatively small at the toe of the upper slope under normal conditions, which can be protected by the aquatic plant survived on the platform. Compared with the revetment using continuous boxes, the new ecological revetment can enhance the anti-wave performance of the structure and achieve significant economic benefits.
