摘要
本文采用弹性柱(桩)支承空间刚体(码头上部结构分段)的力学模型,分析高桩码头的自由振动特性,并按反应谱方法给出计算水平地震惯性力和惯性扭矩的解析表达式。最后结合例题指出惯性扭矩的作用不容忽视。
In this paper, the pile wharf is simplified as a rigid body supported by elastic piles.The free vibration properties of pile wharf are evaluated by means of this simplified model. Then, by using the response spectrum method, the analytical solution is obtained for the calculation of inertia torques and earthquake inertia forces in horizontal direction.Some examples are given and the results are compared with taht by normal method. It is found that the influence of the inertia torques on the stability of wharf can not be neglected.
