摘要
依托萨摩亚阿皮亚港某防波堤工程,结合工程当地石料供应不足、大块石选料与施工困难、开山采石环保要求高以及项目面临工期失控等特点,采用Xbloc+Xbase组合人工块体压脚结构设计,并通过整体物理模型试验对其稳定性进行了验证。试验验证结果表明:斜坡式防波堤采用人工压脚块体替代天然块石是可行的,可满足波浪作用下的稳定性要求,并在相同的波浪条件下斜坡堤堤头圆弧段背浪侧135°~180°夹角区压脚结构相比于堤头其他区域更易失稳,设计中应重点关注。研究成果可供类似工程设计提供参考。
Based on a breakwater project in Apia Port,Samoa,combined with the characteristics of insufficient rock supply,difficulties in selecting and constructing large stone blocks,high environmental protection requirements for quarrying and project schedule risks,the design of a toe structure utilizing Xbloc+Xbase artificial armor units was introduced.The structural stability was validated through comprehensive physical model tests.The test verification results show that replacing natural stone blocks with artificial armor units in the toe sturcture of sloping breakwater is technically feasible,which can meet the requirements of stability under wave action.Furthermore,under identical wave conditions,toe structure on the leeward side(135°~180°angular zone)of the round head of sloping breakwater is more susceptible to instability than other regions of the breakwater roundhead,which should be paid attention to in the design.These findings can provide a reference for similar engineering designs.
