The study reviewed general concepts of the constitutive model Hardening – Soil and its parameters, and separated these parameters into two groups: parameters calibrated to the stress-strain curve of consolidated ...
Web4 sept. 2024 · Bishop (1955) developed a more revised method for analysing circular slip which improved the accuracy of the resultant FOS. This method is still used widely in … WebA new method is proposed for the optimum design of nailed soil slopes. A rigorous method of stability analysis, namely the Janbu's method, is modified in the limit equilibrium formulation, considering the effect of reinforcement. Only the tensile resistance of the reinforcement is included and the effects of shear and bending neglected.
WebThis study investigates the displacement-dependent lateral earth pressure of sandy soil in active state. 3D DEM numerical simulations of plane strain unloading test (unloading in the minor principal stress direction) are carried out firstly to acquire the hyperbolic stress–strain relationship of sandy soil. The initial modulus of sandy soil is observed to increase with … WebIt has been found that genetic algorithm is a robust search technique which often gives global solution. In the present study, genetic algorithm has been used to locate the critical slip surface of non-homogeneous slope in conjunction with slope stability analysis method developed by Janbu (1973) for generalized slip surface.
