Numerical simulations of the mechanical contribution of the plant roots to slope stability

Abstract

Soil bioengineering methods in slope stabilisation are becoming more and more popular, when ecological solutions are desirable. Simple, numerical models were created in order to assess the mechanical contribution of the roots reinforcement to slope stability. Two- and three-dimensional analyses were conducted for different geometries of root architectures and different soil conditions. Obtained values of a factor of safety (FOS) are compared and discussed. From these data, it is possible to determine, which root reinforcement cases have the greatest impact on the stability of the slope.
