UPPER-BOUND LIMIT ANALYSIS OF REINFORCED SLOPES FOR CLAY SOIL

摘要

An upper-bound limit analysis approach is applied to determine the limit height of reinforced slopes for clay soil. The reinforcement is uniformly distributed over the height of the slope, and tensile failure is occurred in each layer. A rigorous upper bound to the slope height is calculated. Two methods were described to considering the influence on the limit height from pore-water and the sensibility of influence on stability of slopes from pore water and cohesion of soil is discussed.
