摘要：

借鉴日本东京湾的隧道分析方法，提出了适合于本课题的隧道分析的计算模型，即用等效质量-弹簧系统代替地基切片，隧道用能承受剪力、弯矩和轴力的梁代替．数值仿真表明，隧道与风井接头处的轴力、角位移、剪力较大．如果总体设计允许的话，建议各段隧道的长度不宜相差太大，以减小地震波作用下隧道接头的动力相对位移和内力．

Abstract:

A spring-mass model was presented for numerical analysis of the response of a tunnel under the Huangpu River to actual earthquakes. In this model the soil is divided into many strips and each strip is simplified to a mass-spring system. The tunnel is treated as several beams connected by linear springs in longitudinal and lateral directions. The tunnel is connected with the soil also by linear springs in the same two directions. So the total tunnel-soil system is simplified to a rigid multibody system. The vibration response of this system during earthquake can be obtained by a computer program DAMB. From the numerical results it is recommended that every segment of the tunnel should be in the same length in order to reduce the no nuniform displacement and stress between the tunnel segments.

Key words: subaqueous tunnel, antiseismic design, vibration analysis, multibody system dynamics
