摘要
在防波堤、引堤工程中,常通过设置防浪墙以降低实体堤堤身高度,节省工程造价。防浪墙作为挡浪结构,其稳定性直接影响掩护范围内人员及设备的安全。而中长周期波作用下防浪墙前波浪力分析是防浪墙稳定分析的重点同时也是难点。通过中外不同规范针对中长周期波浪作用下的防浪墙前波浪荷载进行计算分析,并结合物模试验实测值对中外不同规范设计结果进行复核。分析结果表明:中外不同规范的计算结果与物模试验实测值均存在较为显著的偏差,在项目实际设计中,按照规范公式拟定的防浪墙断面需进一步采用物模试验进行验证。
Wave wall is usually adopted for the breakwater and causeway projects,this can reduce the height of structure and save project cost.As the wave block structure,the stability of wave wall affects the safe of personnel and equipment within the cover scope directly.The analysis of wave force in front of wave wall under the action of medium long period wave is the key and difficult point of wave wall stability analysis.After the analysis of wave force in front of wave wall under the action of long period wave by Chinese and foreign codes,and the analysis results by Chinese and foreign codes is rechecked through the physical model test.The analysis results show that there is a significant deviation between the calculation results of different codes and the physical model test result.In the actual design of the project,the cross section of the wave wall according to the codes needs to be further verified by the physical model test.
