摘　　要：基于结构力学中超静定结构的相关理论,讨论了预应力次内力产生的机理及其对结构的影响,进而提出合理利用次内力的设计思想。On the basis of relevant theory of hyperstatic structure in structural mechanism, the paper discusses the mechanism of secondary interior force caused by prestressing and it's effect on structures. As a result, a new design idea of using secondary interior force effectively is presented.

关 键 词：预应力混凝土 超静定结构 次内力 结构力学
