To view prior sessions, across multiple topics, see Recordings On-Demand. Every sequence of the model was to investigate for the stability analysis purpose with various slope angle with variable slope height were taken into account. In this study different types of sequence modelling were conducted here. PLAXIS is a finite element program, developed for the analysis of deformation, stability and groundwater flow in geotechnical engineering (Brinkgreve et al.

Users participating in this interactive course are asked to bring their questions so that we can try and clarify how PLAXIS can handle your case.īentley Answer Hours are open to all Bentley users, free of charge. The stability analysis of the slope has been done here by Finite Element Method using PLAXIS-2D. The geometry of the embankment’s crosssection was imported to PLAXIS 2D where a model was built. Pedro Reis, Associate Technical Support Engineer, Geotechnical Engineering at Bentley Systems, Inc. Host/Presenters: Stefanos Papavasileiou, Manager, Technical Support, Geotechnical Engineering at Bentley Systems, Inc. answer some questions we see often in our support inbox.Figure 15: Factor of safety for the slope stability. explain about various ways of performing checks to ensure your model is ready for a calculation Table 4: X for both Cases using the built-in phi-c reduction scheme in Plaxis and a user defined version.

Plaxis 2D and 3D is best suited slope stability software if you wish working with finite. Learn More OpenGround Cloud OpenGround Cloud is a secure enterprise cloud collaboration platform for geotechnical data management, which empowers teams with access to current and historical project data in a dynamic cloud-based environment. Plaxis is the best for the slope stability, the finite element show you the a 3D of the slope stability. In this session Bentley will provide a short presentation on how PLAXIS 2D and 3D handles the model geometry, and: PLAXIS LE Enhance 2D or 3D limit equilibrium slope stability analysis with related unsaturated seepage groundwater flow estimation or stress analysis. In all cases the geometry will be automatically intersected and a finite element mesh will be generated before a calculation is performed with the goal of handling the geotechnical design. If SF <1.5 is not stable and need a treatment. Stage 4 the safety factor rate (SF) can be seen as follow: a. Calculationof slope stability by using PLAXIS2D v-8.6 4. Calculation of slope stability manually withFelleniusmethod b. PLAXIS offers many ways of defining the model geometry. The slope stability analyzed by two steps of calculations, namely: a.

Additionally, it is shown that the initial stress field does not affect the FoS when using a Mohr-Coulomb failure criterion.Answer Hour programs are short, interactive presentations with Bentley experts designed to address topics and issues that are currently trending among users and administrators. Further studies highlight the advantages of using an adaptive mesh refinement to determine FoSs. When using the modified approach, both the SRFEA and the FELA provide very similar results. Suggestions to overcome this problem, proposed by Davis (1968), lead to conservative FoSs therefore, an enhanced procedure has been investigated. The FELA on the other hand provides rigorous upper and lower bounds of the factor of safety (FoS) but is restricted to associated flow rules. If the relative shear stress in the plastic phase is studied in the PLAXIS output program for the unloaded 2D-case of group C (upper picture in Figure 19), the. Displacement-based finite element analyses using a strength reduction technique suffer from numerical instabilities when using non-associated plasticity, especially when dealing with high friction angles but moderate dilatancy angles. The construction of slopes was simulated in 7 stages of equal height for all the slope inclinations. The paper compares the performances of strength reduction finite element analysis (SRFEA) with finite element limit analysis (FELA), whereby the focus is related to non-associated plasticity. PLAXIS 2D was used for stability analysis. In comparison to limit equilibrium methods, numerical analyses do not require any definition of the failure mechanism a priori and enable the determination of the safety level more accurately. In recent years, finite element analyses have increasingly been utilized for slope stability problems.
