预应力锚索框架型地梁的内力计算

A Calculation Method of Internal Force for Frame Foundation Beams with Prestressed Anchor Cable

提出了预应力锚索框架型地梁内力的一种计算方法 ,即把框架地梁分解成单梁 ,按温克尔 (Winkler)假定计算各单梁的内力 ,由此进行框架地梁的尺寸和配筋设计。在内力计算中同时考虑框架地梁的锚索张拉阶段和工作阶段。

A calculation method of internal force of frame foundation beam with prestressed anchor cable are presented It is mainly shown that internal force of the frame foundation beams should be respectively calculated at the pulling anchor cable stage and long term working stage The worst combination of internal forces at the two different stage should be as the basis of design for the frame foundation beams Being calculated, the frame foundation beams may be disconnected to two types single foundation beams At the pulling anchor cable stage, the internal force of can be calculated by Winkler hypothesis; on the long term working stage, internal force of the single foundation beam can both be calculated as inverse continuous beam on cutting slope surface operated by slope pressure with linear distribution Calculation procedures of the internal force of the frame foundation beam are given in detail by practical projects
