Automatically mesh to create a finite element mesh almost immediately. Define everything from complex soil profiles or geological cross-sections to structural elements, such as piles, anchors, geotextiles, and prescribed loads and displacements. Well proven and robust calculation procedures ensure converging calculations and accurate results.Įfficiently create models with a logical geotechnical workflow. With plastic, consolidation and safety analysis calculation types, a broad range of geotechnical problems can be analyzed.Ĭonstitutive models range from simple linear to advanced highly nonlinear models through which soil and rock behavior can be simulated. Accurately model the construction process by activating and deactivating soil clusters and structural elements in each calculation phase with staged construction. The Curve manager enables graph creation, plotting various types of results from available calculation data. Leverage powerful and versatile post-processing and display forces, displacements, stresses, and flow data in contour, vector, and iso-surface plots in various ways.Ĭross-section capabilities allow for a more detailed analysis of the results. When using predictions determined by PLAXIS, it is first necessary to validate the adopted soil model and finite element model against measured field data to ensure that PLAXIS predicts true behaviour with sufficient accuracy.Įmail This BlogThis!

When using embedded piles, however, the conditions of the top of each embedded pile can be selected as free, fixed or pinned. To the writer's knowledge, there is no way of modelling a pile raft with pinned conditions at the pile heads using volume piles. While it is possible to create a half-pile in the pile designer, it is not possible to create a quarter of a pile. The pile group can be modelled as half a group by using one line of symmetry or can be modelled using a quadrant of a group by using two lines of symmetry i. First of all, taking advantage of the symmetry boundaries in PLAXIS can greatly reduce the number of piles you need to model and thus the number of elements in your finite element model assuming the pile group is symmetrical. Lane 5000įor pile groups larger than 40 piles, however, it is possible to model these groups by using a couple of tricks. In order to prevent this stage having any effect on the adopted soil properties, it is advisable that the unit weight of the dummy material is set to 0. One final tip - if the adopted soil model is a nonlinear soil model for e. Pile group loading by placing a compressive or tensile uniform distributed load on the top surface of the pile cap. Pile installation by changing the soil within the volume pile to the properties of concrete.Įxcavation of the dummy material around the piles to the required depth i. Thus the stages of analysis for a free-standing pile group are as follows. The top dummy layer is then excavated so that the piles are left extending above the soil surface. The user then converts the soil within the pile cross-section to the properties of concrete. One trick to get around this is by creating an extra layer of soil above the ground surface a 'dummy' layer. It can be difficult, however, to have these piles extend above the ground surface where there is no soil volume. Smart selection of line elements in PLAXIS 2D Input

In order to install a pile, PLAXIS first needs a volume of soil to convert to the properties of concrete during the pile installation phase.
