为掌握超大口径全可动射电望远镜结构抗震性能特性,以待建的110 m全可动射电望远镜为研究平台,以三水准原则为控制目标,运用时程分析法对望远镜结构在小震和大震作用下的受力性能进行分析,给出了结构在多遇地震作用下、多遇地震与静力组合工况下以及罕遇地震作用下的关键力学响应指标,评估了结构在地震作用下的安全性能。

英文摘要：

In order to understand the aseismic ability of large aperture all-movable radio telescope structures, the proposed 110 m fully-steerable radio telescope to was used as an example. Based on the three levels in earthquake fortifica- tion as control condition, the mechanical properties of the telescope structure was analyzed under situations of frequent and rare earthquakes by using time-history method. The mechanical responsive targets which are crucial to the structure under activities of frequent earthquakes, frequent earthquakes combined with static unitized load mode and rare earthquakes were calculated. The safety properties of the telescope structure were also evaluated under different kinds of earthquakes.
