Theory and Experiment Research on P-S Curve of Anchor in Soil

摘要

Based on the shear displacement constitutive relationship of the interface between anchorage body and surrounding soil, the load transfer function method is applied to build a elastic-plastic space model. Accordingly the relationship between drawing force and displacement of prestressed anchor is analysed to acquie theoretical formula of P-S curve. The pullout test is carried out on six prestressed anchor in soil to get P-S curves. The experimental results agree quite well on the theoretical results.
