  1. Strip - shape underground structures such as the tunnels and tubes for various uses can be treated as a beam on elastic foundation under earthquake condition ， although there exists soil - structure interaction ， the foundation soil vibration is dominant in other words ， analysis of earthquake response of the soil is essential to this end ， simplified models ， ( i. e equivalent mass system models based on some equivalence criteria ) are proposed ， instead of a general 3 - d continuum model in this study ， equivalence criteria are proposed and the simplified models are compared the single - mass - string model is proved to be valid and therefore applied to the analysis of earthquake response of the pearl river immersed tunnel
