With the increase of the reinforced length, the probable destroyed cross because of the shearing moved away from the panel. The maximum pulling stress focused on the lower half of the reinforced soil retaining wall. The simulation and analysis showed that with the increase of reinforced length, the side displacements of the panel and the pulling stress in reinforced layers decreased gradually. In this paper, a reinforced soil retaining wall which was 60 meters high was set up to study the effect the reinforced length had on soil retaining wall.

The results showed that the finite difference software FLAC 3D could simulated very well. Then the results were compared with those which were derived from limited balance method. The developed constitutive model can provide support for the seismic disaster assessment of soft soil site and slope under large strain condition.A finite difference software (FLAC 3D) was used to carry on numerical simulation of reinforced soil retaining wall which had observed engineering data. If the cyclic softening is taken into account, the calculated shear strength is significantly reduced, and the convergence of the model is improved when the shear stress of the backbone curve can be continuously transferred to the softening main curve. When the shear strain is larger than >Ä .01%, the modified model describes better the damping ratio-shear strain relationship than Hardin-Drnevich model and Davidenkov model. It is shown that the calculated backbone curve is consistent with the theoretical formula, and the calculated dynamic shear modulus ratio and damping ratio are in good agreement with the experimental data. NUMERICAL SIMULATION BY FLAC3D Because of the FLAC3D is widely applied in rock mechanics and dynamic issues, this paper analyzes the seismic dynamic response of ground surface above mined-out area by FLAC3D. A secondary development of the constitutive model is implemented into the FLAC3D platform, and the proposed procedure is verified by the theoretical formulation and the experimental data available in the references.

On the basis of existing nonlinear dynamic constitutive models, a method to deal with the cyclic softening is proposed. In geomechanics, FLAC3D is a widely-used numerical code coupled with TOUGH or TOUGHREACT in various applications such as CO 2 storage in a geological formation, CAES, fault reactivation, high. Specialities: Geotechnical designs, AutoCAD, Rhino 6. Qualification: Civil Engineering (First Class Honours) / Commerce (Distinction) at UNSW. Therefore, it is necessary to study the nonlinear dynamic constitutive model considering cyclic softening in order to analyze the stability of seismic slope under complex conditions. William (Shunan) Wei is a highly motivated geotechnical engineer who has contributed to projects such as Rozelle Interchange - Westconnex, Sydney Football Stadium, The Ribbon, and Pacific Highway Upgrade. The focus of this tutorial is to provide you with a basic famil. onset of significant strains or strength loss in soils during earthquakes. The effect of earthquakes on the stability of the subway station and ground motions of surrounding rock masses, plays a key role in the seismic design of the subway station to avoid severe damage to subway station itself and adjacent structures. This tutorial steps through the actions necessary to quickly create and solve a FLAC3D model. Implementation of nonlinear dynamic constitutive model in FLAC3D with. Catastrophic failure of slopes often results from cyclic softening, i.e. researchmap is provided by Japan Science and Technology Agency.
