| Abstract: | The anchor plug nerving is an universal problem existing in construction of prestressed reinforced concrete,is also one of main reasons having effect on accuracy of prestressed value.The paper's introduction centres on the methods for in specification stretching of prestressed reinforcements,the reasons for anchor plug nerving,the influence of anchor plug nerving on prestressed value as well as the treatments for serious losses in prestressed value caused by it. |
| Keywords: | Anchor plug Nerving Prestressed losses Stress controlling Overstretching |
