Abstract
A brief description of the recent advances of the soil nailing technique in the world is given in this paper
and the development of this technique in some typical countries and regions are compared and summarized.Simultaneously
the common methods
devices and the principles of field and laboratory soil nail pullout tests are introduced
and the influence factors affecting the pullout test results are discussed.On this basis
some theoretical models
including the ideal elasto-plastic model
the bilinear model
and the hyperbolic model
are presented and evaluated. The research advances of numerical analysis methods that have been utilized for simulating soil nail pullout behavior
such as the finite element method(FEM)
are summarized.Finally
some problems in the study on soil nail pullout performance and the new research trends are introduced.Detailed recommendations are provided for further study on soil nails made of new materials and their time dependent characteristics.
