Consequently, on the basis of non - winkler foundation model, a finite - element method that utilizes foundation flexibility matrix into iterative calculation is proposed in this paper originated from the item " the optimal design theory and research of pile capping beam " sponsored by natural science fund of hunan province, which the continuity of soil mass can be accounted for under various boundary conditions, different loadings and irregular beam characters
本文結合湖南省自然科學基金項目「樁基承臺梁優化設計理論與方法研究」 ，針對非文克爾地基（半空間、線性變形層或單向壓縮層地基模型等）上的樁基承臺梁，提出一種利用地基柔度矩陣來進行迭代的有限單元法，可充分考慮梁下土體的連續性，並對基礎與土體脫開、承臺梁截面變化、梁體邊界條件復雜、上部荷載類型變化以及梁下基樁承載力差異等情況進行分析計算。 -
Then the solving procedures of these bies by the rwg functions based moment method are elaborated, and the method of modeling complex objects built of arbitrary line, surface and volume structures is developed. in order to solve realize antenna and circuit problems, methods of adding excitations and concentrated loadings with moment method are deceloped, and matrix pencil ( mp ) method is used to deembeded the s prameters of antennas and circuits from the computed current distribution. some numerical results of practical complex antenna and scattering problems are presented to illustrate the veracity and effectiveness of the method
在第一部分中，首先從電磁場的基本理論出發，基於等效原理和邊界條件以統一的方法建立了用於分析金屬、介質及金屬與介質混合結構的邊界積分方程，並歸納和比較了各類積分的適用范圍和優缺點;在此基礎上，給出了使用基於rwg函數的矩量法求解各種邊界積分方程的一般過程;研究了具有任意線、面、體組成的復雜結構的電磁建模方法，並給出了各種多面連接情況下基函數和未知量的選取方法;研究了使用矩量法分析電路、天線問題時集總元件和激勵源的處理方法，並基於矩陣束方法（ matrixpencilmethod ）提取了電路和天線問題的s參數;最後通過分析一些工程中的復雜金屬天線問題和具有「金屬與介質混合結構」的散射和天線問題驗證了方法的準確性和高效性。 -
The stiffness matrix is kept constant in all incremental loadings and each iteration. only force vector is changed. so, the efficiency of computing is approved dramatically
由於採用了常剛度法，則在所有荷載增量與每次迭代中剛度陣均不變動，只需改變右端荷載向量即可，因而顯著地提高了計算效率。
