椭圆形支护结构的简化计算

Simplified calculation model for ellipse retaining structure

椭圆形支护结构是较为简单的拱形支护结构的一种,具有计算简单、经济合理优点,但关于其内力的设计计算方法研究的还很不够。本文以弹性板壳理论为基础,分析了椭圆形"壳体"支护结构的内力特点和设计控制内力的计算方法,对此类支护结构的工程应用具有一定的参考价值。

Being a kind of arch structure, the ellipse retaining system bears the lateral load rationally and frugally, however, the internal force analysis and the corresponding design procedure has not been fully studied. Based on the elastic shell theory, the internal force analysis features in ellipseretaining structure are summarized, and the method to determine the controlling design force is put forward, which may be used as a reference in similar project.
