体外预应力加固混凝土梁的探讨

On exploration for external prestressing reinforced concrete beam

阐述了体外预应力加固方法的优缺点,对国内外应用体外预应力技术的承载能力、应力增量问题以及摩擦损失的研究现状进行了介绍,指出了体外预应力技术研究现状的不足及未来的发展方向。

The paper illustrates the advantages and disadvantages of the external prestressing consolidation methods, introduces the research at home and abroad on the loading capacity and the stress increment of the external prestressing technical of the concrete beam, and the status of the friction loss, points out the shortages of the status of the external prestressing technique and its future development.
