Designing dewatering systems to keep pits dry and stable. It helps predict the necessary pumping rates and the impact on surrounding structures.
PlaxFlow add-on (included in the Ultimate tier) enables advanced time-dependent simulations, such as rapid drawdown in dams or seasonal water table fluctuations. www.dcodes.io +3 Core Capabilities Time-Dependent Analysis: Unlike steady-state analysis which assumes conditions remain constant, PlaxFlow simulates how pore water pressure changes over time due to external factors like rainfall or pumping. Unsaturated Soil Behavior: It accounts for the unsaturated zone above the phreatic level, using hydraulic models to simulate how soil permeability varies with suction and degree of saturation. Fully Coupled Flow-Deformation: This advanced feature calculates changes in pore water pressure and soil deformation simultaneously. It is essential for modeling complex scenarios like the consolidation of soft clay or the stability of dams during rapid drawdown . Key Technical Features Hydraulic Models: PlaxFlow implements several standard models to describe the storage and flow of water in unsaturated soils, including Van Genuchten and Mualem models. Boundary Conditions: Users can define complex hydraulic boundaries, such as precipitation, infiltration, and time-dependent head changes (e.g., rising river levels). Integrated Workflow: It operates within the standard PLAXIS 2D environment, allowing for a seamless transition between geometry creation, mesh generation, and flow analysis.
