摘要
本文着重叙述了在预应力轨枕模型和拉压双应力桥梁模型上采用环槽法和盲孔法测量模型预应力的方法,以及有关的分析计算结果.
Grooving and hole drilling method used in measuring prestressing force in prestressed concrete structure members are described.Models of Prestressed sleeper and dual(stretched and compressed)prestressed bridge beam are measured.The dispersion of measuring data is small.Results obtained agree very well with those from calculation,their relative error is less than 20%.
