摘要：
A semi-analytical method for the treatment of a regular semi-infinite fluid channel in a three-dimensional dam-reservoir interaction analysis is proposed. Based on an analytical frequency-domain solution for the open fluid domain an accurate representation of radiation damping is achieved. A set of ordinary differential equations to represent the channel in a coupled time-domain analysis is obtained by means of the mixed variables technique.
