摘要
通过在预应力安全壳实体上进行摩擦试验 ,验证预应力钢束受力计算时所采用的摩擦系数与现场实际施工中所产生的摩擦系数是否一致 ,从而准确地确定预应力值 ,保证预应力体系的工程质量。
Engineers made some friction tests on the prestressed safety shell in order to verify whether the friction coefficient adopted in the bearing calculation of prestressed steel strands is equal to the friction coefficient existed in practical on-site construction,and then they could determine exactly the prestressed value and ensure construction quality of the prestress system.
