无限元法是近几年发展起来的一种新的计算方法,它特别适用于求解地下结构一类相互作用问题。在本刊上刊登的“内爆炸荷载作用下地下竖井的动力响应”一文(以下简称原文)是该法在抗爆结构上应用的一次尝试,引起大家广泛兴趣。我们很高兴看到吴逸群等同志在此基础上又做了一些补充工作,提出了自己的看法(以下简称吴文)。下面就有关问题进行一些讨论。
The infinite element method is a new calculation method developed in recent years. It is particularly suitable for solving a type of interaction problem in underground structures. The article “The Dynamic Response of Underground Shafts Under the Effect of Internal Blasting Loads” published in this publication (hereinafter referred to as the original) is an attempt to apply this method to anti-knocking structures, which has aroused widespread interest. We are very pleased to see that Wu Yiqun and other comrades have done some additional work on this basis and put forward their own views (hereinafter referred to as Wu Wen). The following discussion on related issues.
