预应力张拉伸长值的测定与异常情况的分析
Determination of the prestressing elongation and analysis of abnormal phenomena
【摘要】 从理论上分析了造成预应力张拉伸长值偏大或偏小的原因,并结合工程实践论证了本文分析的合理性。
【Abstract】 The cause is analysed,which leads to longish or shortish preactical prestressing elongation as compared with theoretical it,and the cause analysis has been proved to be reasonable in project practice.
