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

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.

Key words:pressure-dispersive anchor; equal displacement tension method; equal load tension method; acceptance test
