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
條裝地下結構如隧道、各種埋設管道等一般可看作彈性地基梁進行靜力及動力分析在地震條件下，結構與土相互作用，但土的振動成為主要因素為分析土的地震響應需把基土這一三維連續體作簡化處理，簡化成為等效多質點模型本文著重探討這種簡化模型的建立方法，推導等效方程，通過幾種簡化體系的分析比較，論證單質點串體系的合理性，並將其應用到廣州黃沙芳村珠江水下隧道工程的地震響應分析，為抗震設計提供依據
