  • 使用后期处理进行结果分析

    • 利用功能强大、用途广泛的后期处理,并以各种方式显示轮廓图、矢量图和等表面图中的力、位移、应力和流动数据。横截面功能可以对结果进行更详细的分析。数据可以从表中复制,也可以通过基于 Python 的脚本来复制,以便在 PLAXIS 以外进行进一步处理。曲线 (Curve) 管理器可创建图形,并根据可用的计算数据绘制不同类型的结果。
  • 评估应力和位移

    • 通过分阶段施工,在每个计算阶段激活和停用土壤团簇和结构元素,准确地对施工过程进行建模。通过使用塑性、固结和安全分析计算类型,可以分析多种类型的岩土工程问题。本构模型的范围包括从简单的线性模型到高级的高度非线性模型,通过这些模型可以模拟土壤和岩石的特性。经过验证且稳定的计算程序可确保收敛计算和精确结果。

  • Dynamic with consolidation calculation type

    • Simulate the coupling between soil deformations and transient seepage in the dynamic loading phase. Using this new, advanced calculation type offers generally improved stress predictions and accounts for both eventualities of accumulation and dissipation of excess pore pressures during earthquakes.
  • Field stress per cluster

    • The field stress initial calculation type allows for direct specification of in situ stress conditions on a volume of soil. It is now possible to assign a different field stress property to individual soil volumes and borehole layers, allowing you to independently input the initial stress state by magnitude and orientation for each of those clusters. The cluster-based field stress complements the global field stress and makes it easier to define the in-situ stress for geological models. This allows easily modeling non-uniform deepground conditions, such as those encountered in deep tunneling or reservoir geomechanics.
  • Girder definition in tunnel designer

    • Tunnels are often reinforced with transverse ribs, which can now be modeled as curved beam elements located at specific intervals in the 3D tunnel designer. The option to add transverse girders, together with plate and volume lining, rockbolts, and umbrella arches, enables modeling complex tunnel reinforcement systems. Girders are a natural component in the slicing and sequencing features of the tunnel designer, enabling you to define the entire construction sequence.
  • Line pass / Cross section curves

    • Create cross-section curveplots from any arbitrary line cross section, structural element, or centerline generated from the structural forces in volume piles capability. It allows you to create a single curveplot to compare how the settlements at the surface level evolve for multiple phases, or to compare the bending moment along the length of a diaphragm wall or tunnel lining (either modeled as plates or volume elements) across multiple phases simultaneously.
  • Loft polycurves and blend surfaces

    • Both these features can be used to provide smooth transitions between non-homogeneous sections. The blend surfaces feature generates a continuous surface that joins a set of other surfaces by filling the voids between them. The loft polycurves command fits a surface to a set of polycurves, such as turning a series of spatially located 2D cross-sections into a consistent 3D geometry.
  • NURBS curves

    • Use NURBS curves to model arbitrary shapes in 3D. NURBS curves are automatically generated from a series of successive points. These curves and polycurves can be combined to generate almost any geometry. NURBS curves can also be specified as extrusion paths, which enables the generation of curved linear elements with uniform cross section. For example, a cross section that is defined by a polygon or polycurve can be extruded along the trajectory defined by a NURBS curve.
  • Scripting reference manual as a Jupyter notebook

    • Easily learn Python-based remote scripting in PLAXIS with the new scripting reference manual. Sample scripts for each of the commands in PLAXIS are offered in a Jupyter notebook. These samples can be run live in the software to see and understand what happens. You can also edit and rerun the samples and see the effect of your changes, offering a great way of learning-by-doing.
