string model meaning in English
弦模型
Examples
- 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
条装地下结构如隧道、各种埋设管道等一般可看作弹性地基梁进行静力及动力分析在地震条件下，结构与土相互作用，但土的振动成为主要因素为分析土的地震响应需把基土这一三维连续体作简化处理，简化成为等效多质点模型本文着重探讨这种简化模型的建立方法，推导等效方程，通过几种简化体系的分析比较，论证单质点串体系的合理性，并将其应用到广州黄沙芳村珠江水下隧道工程的地震响应分析，为抗震设计提供依据
