摘要
本文针对神户沉箱码头利用有限元软件ANSYS构建了三维计算模型,分析了沉箱码头的结构自振特性并计算了阻尼值。在elecentro波、kobe波、emc波三种地震波激励条件下,采用现行规范拟静力分析法和瞬态动力时程分析法计算了沉箱码头的应力应变情况、沉箱后壁加速度分布系数、地震惯性力标准值、地震动水压力标准值并做了结构抗震验算,同时也对比分析了两种方法计算结果的差异,可为现行规范的修改提供参考依据。
Finite element software ANSYS is used to establish three-dimensional calculation model of Kobe caisson quay wall.The natural vibration characteristics are analyzed and the damping value is calculated.Under the conditions of three different seismic waves,that involves elecentro wave,kobe wave and emc wave,the standard quasi-static analysis and transient dynamic time-histories analysis methods are applied to calculate stress and strain of caisson quay wall,acceleration distribution coefficient of the back wall,standard values of seismic inertia force and hydrodynamic pressure.The structural anti-seismic is also checked.The results with two methods are contrastive analysis,which provides reference for modifying the current technical specifications.
