Rearch On The Application Of The Stress Remolding Method To The Slope In Landside Correction

There are a lot of methods that could be applied to slope stability analysis. We can use different mechanical model and different method to analysis different slope. Different analysis purpose and different precision need different ways. At present, Limit Equilibrium Method of Slope Analysis is the most pervasive way. The foundation of Limit Equilibrium Method is based on Mohr-Coulomb strength criterion. The basal specialty of this method is just to consider static equilibrium and Mohr-Coulomb failure criterion of soils. It means to get solutions by analyzing the force equilibrium at the moment while slope encounter failure. In common cases, slope stability is not a static problem. Limit Equilibrium Method makes some hypothesis and the stability analysis changes into static problem. This worked method would damage the strictness of solution.For landside correction in excavation project, this paper is based on the Stress Remolding method and commences to analyze the slope in excavation project: Apply loads to the slope and reset the slope in an original stress and make it work like before excavation. By comparing the original stress, the stress after excavation and the reset stress, we may conclude how to remold the stress in the slope in excavation project. Cooperating with expansive anchors, the Stress Remolding method can increase the anti-slide capacity of slope soils. And this method can consumedly reduce the expenses of landside correction. The Stress Remolding method of landside correction completely disengages Limit Equilibrium Method of Slope Analysis. It's a new way and has great academic and practical meaning.
