| 摘要: |
| 护面砌块作为堤坝结构的组成部分，其抗浪能力对堤坝的整体稳定起着重要作用。通过较大比尺物理模型，针对我国堤坝设计的具体情况，对一种新型开孔勾连块体的抗浪稳定性进行试验研究，分析砌块厚度、戗台、波浪周期等因素的影响，得到砌块抗风浪稳定厚度计算式。建议护岸设计中应采用均衡设计的理念，综合考虑波浪荷载，将其平衡分配给护面、垫层和基土，对海岸、河流、大型湖泊和水库等水利工程的护岸和堤坝抗浪稳定设计具有指导意义。 |

| Abstract: |
| The concrete blocks are the major protection structures of the revetment and play an important role in revetment stability under the action of waves. In this study, systemic model test studies on the stability of new type hook perforated concrete blocks under the action of waves are carried out with focus on the practical design of dikes and breakwaters in China. The influence of the thickness of the concrete blocks, berm and wave period on the stability of the concrete blocks is analyzed, and an empirical formula to calculate the stability thickness of the concrete blocks is obtained from analyses of the factors mentioned above. It is found from the analyses that the concept of “equilibrium design” (e. g. the filters are selected for adaption to concrete blocks) should be applied to the design of the bank protection works. And the model test results can be beneficial to the design of the concrete block revetment for coasts, river banks, large lakes and reservoirs and will be a guide to the selection and design of the revetment works. |
