Abstract: In order to investigate the influences of parameters on aseismic behavior of soil nailing system, some shaking table tests are designed and carried out. Dynamic characteristics of the soil nailing system with different parameters (such as nail inclination, nail length, nail space) are studied. It is found that the soil nailing system has good aseismic behavior. The maximum lateral displacement mainly occurs at the abdomen of the slope during the tests, but the displacements at the crest and foot are relatively small. Increasing the soil-nail obliquity will increase the lateral displacement, but increasing the length or reducing the space of soil nail will minish the lateral displacement. The shape of the maximal function belt is polygonal-shape, and the maximum function belt is located in the foreside or middle part of the soil nailing area, which is not the sliding plane appearing under vibration condition.
