摘要
着重介绍了预应力张拉施工中,千斤顶与压力表配套校验后一元线性回归方程的建立、显著性检验、应用及注意事项,通过一元线性回归方程的建立,可以减少重新配套校验的程序,大大节约时间和成本。
The building,significance checking,application and matters need attention of one-place linear regression equation after lifting jack and pressure gauge mating checking in prestressed stretching construction were introduced critically.By building one-place linear regression equation,the rematching checking procedure can be reduced and the time and cost can be saved.
