预应力张拉千斤顶的校验是预应力结构工程中非常重要的环节,其校正的准确度直接影响建立在结构上的预应力值和结构性能,尤其是小预应力值的张拉更应该重视其千斤顶校验的方法:正校与反校。
The calibration of prestressed tension jacks is a very important link in prestressed structural engineering. The accuracy of its correction directly affects the value of prestress and structural performance based on the structure, especially the tension of small prestressed values. The jack verification method: the school and anti-school.
