| 摘 要： | 同济大学4×4m地震模拟振动台是我国引进的第一台技术先进、规模较大的这类振动台。它的基础是由我们自行设计的。本文阐述如何在困难的客观条件下确定基础方案:探讨了各种不同的基础振动计算模型,提出了无限扩展截头锥体模型;讨论了基础结构设计的若干重要问题,如壁板与底板的刚度校核,基础的配筋方法、局部预应力等。振动台二年来运转的情况证明本文提出的设计方法是符合实际的,基础工作状况很好,完全符合设计要求。

| Abstract: | A modern earthqauke simulator was built at Tongji University in 1983. Its foundation was designed by the authors and their partners.
In this paper overall thingking of the foundation under strict surrounding limitations was discussed; several different dynamic analytical models were compared; so called "semi-infinitive top-cut cone model" was suggested and some structural design problems such as reinforcement principle, stiffness check and local prestress of wall and bottom plate were discussed.
The earthquake simulator has been run for more than two years, and the foundation is working very well. The designing method which presents in this paper has stood severe examination in practice. |
