摘要
短束预应力钢绞线在施工中很容易出现超限的问题,即实测伸长值与理论伸长值的比值超出现行公路桥涵规范中6%的规定,分析了超限产生的原因,并提出了在施工中加强控制的合理建议。
In construction, the short prestressed strand is easy to produce the overrun, namely the value of ratio of extensibility measured to theoretical extensibility exceeds 60% stipulated in ＂ Highway Bridge - Culvert Specification in Force＂. The paper analyzes causes for overrun and proposes rationalization proposals for strengthening the control of it in construction.
