摘要
文章依据海塘堤前波要素和设计断面资料,在河海大学水资源及水利工程国家重点实验室、海岸工程实验大厅70 m长的不规则波浪水槽中进行物模试验。通过计算得出毛竹圩大堤控制点位置的波要素,验证和确定海塘达标断面堤顶高程;验证达标加固断面的防浪墙、护面结构、垫层结构、消浪平台、抛石护脚在波浪作用下的稳定性;测定新建深弧形防浪墙墙身和底板在波浪作用下的压力的分布和越浪量,从而验算防浪墙的稳定,就堤防达标加固方案提出了优化建议。
According to the wave elements in front of the seawall and the section design data,the physical model test was carried out in a 70 m long irregular wave flume in the State Key Laboratory of Water Resources and Hydraulic Engineering of Hohai University and Coastal Engineering Experimental Hall.The wave elements at the control point position of Maozhuwei levee are obtained by calculation,and the crest elevation of the seawall section that meets the standards is verified and determined.The stability of the wave wall,protective surface structure,cushion structure,wave dissipation platform and riprap landslide prevention skirting of the reinforced section that meets the standards under wave action is verified.the pressure distribution and wave overtopping of the wall body and bottom plate of the newly built deep-arc wave wall under wave action are measured,so as to check the stability of the wave wall,and put forward optimization suggestions for the reinforcement scheme of the levee.
