In this article, considering the character of the one - dimensioned continuum and the cross - section, the varied quotiety of the strain can be presented as the mode function to identify the damage. and inversion of the elastic wave is presented to detect the injures when the area is the variable of the inversion, for the pip usually buried under the earth or enwrapped into the protection make the detection difficulty by the mode of vibrancy. the influence of the area must be considered if the exactness is the pre - requisition
在論文中，考慮到壓力管道的一維性質，提出用應變模態改變變化率的方法對一維的結構進行損傷識別；同時考慮到在實際的工程和現場測試中，壓力管道大多深埋在地下或者有外在的保護膜，不宜進行模態的檢測，所以也考慮利用彈性波的方法對壓力管道的性質參數和截面性質進行反演識別，從而得到我們感興趣的東西，達到損傷識別；一般，在利用彈性波反射方法進行損傷檢測中，不考慮截面效應對彈性波的衰減影響，這就對損傷檢測造成一定的影響，本文考慮截面效應的影響，通過實驗來確定截面效應系數。 -
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 -
All of these reveal the further properties of the wave propagating in one - dimensional elastic continuum. on phase plane, the qualitative analysis are made, which exhibits four kinds of orbits : the heteroclinic orbit of burgers equation, the homoclinic orbit of k - dv equation, and saddle - foci heteroclinic orbit or saddle - joint heteroclinic orbit of kdv - burgers equation
說明burgers方程在相平面上有相應于激波解的異宿軌道; k ~ dv方程有相應于孤波解的同宿軌道: kdv一buegers方程有相應于振蕩孤波解的鞍一焦異宿軌道和相應于激波解的鞍一結異宿軌道。 -

Consequently, although the initial part of the unloading stress - strain curve might be approximately linear, this did not mean that the system response was elastic, as frequently assumed in continuum theories
因此，盡管在卸載應力應變曲線的初始段約為線性，但這並不意味著顆粒系統的響應如傳統連續力學中假定的那樣為彈性。 -
