文摘:利用有限單元法分析了道路結構的r面波傳播特性：在深度方向上衰減較慢，傳播較深，波動性大.提出了在道路結構動力響應計算中，利用面波來模擬水平向傳播波，利用體波來模擬豎直向傳播波.通過算例來驗證該方法的可靠性和精確性，並利用這一動力響應計算方法分析了道路結構表面波測試中所獲彌散曲線的可靠性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。Fibre optic interconnecting devices and passive components - basic test and measurement procedures - part 3 - 34 : examinations and measurements - attenuation of random mated connectors
