Abstract
Slope protection with 3D geonet is an economic, convenient and eco-friendly technique; and it is increasingly used in practical projects. However, 3D geonet is sensitive to the ambient environment; and it might lose its stability due to rainfall infiltration. In this paper, the overall instability failure of the 3D geonet system under rainfall infiltration is analyzed. By adopting the limit equilibrium method, a slope stability analysis model is established; and the influence of slope angle, rivet space, slope length, rainfall intensity on stability are analyzed, and a formula for calculation of design optimization of rivet space is obtained. The research result would provide technical support for the design and stability analysis of slope protection with 3D geonet.
