Abstract
Soil nailing is an efficient method to stabilize different soil structures. The method has been extensively used for improving stability of slopes. The construction process of Soil nailed walls commonly involve three basic sections: excavation, nail installation and face stabilization. The nail bars are inserted into ground by either drilling or grouting and are usually arranged in both horizontal and vertical directions. Present research intends to understand Soil-nailed wall behavior under dynamic excitations. Employing finite difference method a three dimensional model has been developed in the proper finite difference code. Soil constitutive behavior for dynamic analyses is predicted taking into account soil hysteresis behavior. To simulate nail bars cable structural elements are employed and also liner structural elements will be utilized for shotcrete facing. Dynamic excitation incorporated as semi-seismic harmonic loading is applied at the bottom of the model where represents soil subgrade. The boundary conditions are considered to be antisymmetric during dynamic analyses. Effects of different crucial factors are monitored during investigations. Some parameters such as, input motion frequency, nail inclination, nail length as well as soil strength properties have been examined.
