摘要:: 以某深厚覆盖层上核电护岸工程为研究对象,介绍了护岸抗震稳定分析的原理和分析方法。采用等价线性法对代表性断面进行有限元动力时程分析,得到SL1和SL2地震动作用下护岸结构的加速度响应、安全系数、液化区分布状况以及震后残余变形。通过分析地基不同土层交界面加速度响应变化来研究深厚覆盖层对加速度峰值的动力放大效应影响。

Abstract:: To further research the influence of deep overburden layer on seismic response and stability of nuclear power revetment,taking a deep overburden nuclear revetment engineering has been introduced based on the principle and analysis method of seismic stability analysis of revetment.The finite element dynamic time history analysis of representative sections is carried out by equivalent linear method.The acceleration response,safety factor,liquefaction zone distribution and post-earthquake residual deformation of SL1 and SL2 are obtained.Based on the analysis of the acceleration response of different soil layers,the influence of deep overburden on the dynamic amplification effect of the acceleration peak is studied.The results have reference value and guiding significance for similar seismic revetment.
