摘要
首先论证了水中椭圆柱体湿模态的正交性，然后再利用湿模态展开研究了柱体在地面运动激励下的响应．由于实现了广义坐标解耦，从而得到了一个简洁的解式．
In this paper, the orthogonality for the wetted modes of the underwater elliptical sectioned column is discussed at first. Then based on wetted mode expansion, the response of the column under earthquake excitation is discussed. Since the decoupling of the generalized coordinates is realized, a simple solution of the problem is yielded.
