| Abstract: | Interlayer sliding plays an important role in the stability analysis of geofabriform tailings dam. In this paper, failure mode of geofabriform dam body was studied, especially for sliding failure between tailings bags. With the use of contact elements applying to simulate the mechanical property of interlayer contacting of tailings bags and strength reduction method, gradually sliding and destruction process of soil bags interlayer was obtained and analyzed. Research results have a guiding meaning to improving the anti-slide stability of geofabriform tailings dam. |
