摘要 结合某核电站防波堤,应用动力弹塑性分析方法,考虑结构间的动态接触作用,分析了防波堤的地震响应特性和破坏机理。通过研究双向地震作用下结构的位移响应、残余变形及塑性剪切应变等,给出了地震过程中防波堤的破坏形式,说明了竖直向地震动输入对防波堤震后沉降影响显著,并重点分析了挡浪墙最大位移响应及震后残余变形。同时分析了地震动卓越频率、地震动峰值及护坡长度参数变化对防波堤地震响应的影响规律,研究结果为防波堤设计、安全评价和抗震措施研究提供了理论基础。 Based on the dynamic elasto-plastic analysis method, the seismic response and failure mechanism of a breakwater of a nuclear power plant under earthquakes were analyzed. The failure mechanism was investigated through studying the plastic shear strain, the permanent deformation and the displacement response considering the seismic wave input of one-direction and two-direction during earthquakes. The main concerned aspects were the maximum displacement response and the permanent deformation of the wave barrier. The results showed that the vertical seismic input has obvious impact on the declination of the breakwater; at the same time, the influences of the length of the slope protection, the ground motion peak and the remarkable frequency on the failure modes of the breakwater are systematically analyzed. The results provided a theoretical basis for design of a breakwater, its safety assessment and the choice of aseismic measures.
