边界元和分层总和法联合解弹性地基板

Calculating the Plates on Winkler’s Foundation by Boundary Element Method and Layerwise Summation Method

用无奇点边界元法和土力学中的分层总和法联合处理弹性地基上的薄板,求解板上选点的挠度,从而求得板的内力。利用了两种方法的优点,使求得的结果精度高且更符合实际。

Solving the thin plates on Winkler＇s foundation by the nonsingular boundary element method and the layerwise summation method, the deflection of the given point of the plate can be obtained. The internal force of the plate can be got. The application of the virtue of the two methods makes the results that we get more comply with the fact. An example shows the result is precise and more conformed with the practice.
