压力分散型锚索的验收试验分析与检验标准研究

Analysis on Acceptance Test of Pressure-dispersive Anchor and the Study on Related Test Standards

摘要:

在当前压力分散型预应力锚索（杆）的验收试验相关规程中，对总位移量控制范围没有明确规定，使得实际施工验收无所适从。通过对等位移和等荷载2种张拉法的比较，对压力分散型预应力锚索在验收试验中的总位移量的控制范围进行了研究，并结合实际锚索验收试验给出控制范围的建议值，供该类型锚索验收试验相关研究及规范取值参考。

Abstract:

The control range of total displacement is not clearly stipulated in the present correlative regulations about the acceptance test of pressure-dispersive. By comparing the tension methods of equal displacement and equal load, the study is made on the control range of total displacement of pressure-dispersive anchor in acceptance test, and some suggested values of the control range are put forward according to the practical acceptance test, which can be reference to related studies on the similar anchor acceptance tests and values determined for standard.
