Study on uplift test of pressure-dispersive prestressed cable in slope reinforcement project

Abstract

With the background of a reinforcement slope project in the Wan-Ping expressway (Henan, China), this paper studies the uplift test of the non-adhesive pressure-dispersive prestressed cable. The determination method of test parameters and the whole test process are expatiated. The result shows that there are elasticity phase and plastic phase in the P-S curve relating the tensile strength to the end displacement of the cable. Some problems on the test are also analyzed. The results obtained from the study enrich the data and experience of uplift test for this kind of anchorage cable and have important reference value. © 2008 Science Press Beijing and Springer-Verlag GmbH Berlin Heidelberg Geotechnical Engineering for Disaster Mitigation and Rehabilitation.
