自本刊1977年《地道桥专刊》上发表了“弹性地基上框架”的计算方法后,引起不少读者的兴趣,但由于这个方法和传统的结构力学方法(如力法、位移法和弯矩分配法等)有所不同,也使一些读者对它抱怀疑态度,认为这个方法没有很好地考虑上部刚架与底板的共同作用,所以计算结果不能保证静力平衡或变形协调等等。其实这个方法是完全符合结构力学基本原理的。其所以得出不平衡或不协调的结果,是由于在计算过程中,基本结构选取得不当。
Since 1977, published in “Road Bridge Special” on the “elastic foundation on the framework of” calculation method, aroused many readers interest, but because of this method and the traditional structural mechanics methods (such as force method, displacement method and bending Moment distribution method, etc.) are different, but also make some readers skeptical of it, that this method is not well considered the interaction of the upper rigid frame and the floor, so the results can not guarantee static balance or deformation coordination and so on. In fact, this method is in full compliance with the basic principles of structural mechanics. The result of its imbalance or uncoordination is that the basic structure was improperly selected during the calculation.
