Feflow Pdf This is a 2d numerical model that represent the seepage flow in a tunnel with feflow v 6.2. Based on geological and hydrogeological conditions, the finite element subsurface flow system software is used to simulate and predict the development of the natural seepage field and dredging.
Tunnel Seepage Drain Calculation Report Seepage Assessment R1 Pdf Based on geological and hydrogeological conditions, the finite element subsurface flow system software is used to simulate and predict the development of the natural seepage field and dredging construction conditions of the seepage field on the west qinling 1# tunnel area. The feflow 6.1 training manual provides comprehensive guidance on modeling subsurface flow and transport processes using the feflow software. it includes sections on model scenarios, problem settings, simulation runs, and postprocessing, along with advanced topics such as dam seepage and saltwater intrusion. In this tutorial, you are going to learn the basic steps to set up a 3d hydraulic model of groundwater flow with feflow. feflow has an implementation of darcy equation (for saturated flow) and richards equation (for unsaturated flow), which are solved by finite element methods. The 'seepage face' boundary condition was set in the nodes of the tunnels. on surface, there are some small creeks as well and they were modeled by using the same bc.

This paper focuses on a karst water rich tunnel in chongqing and establishes a seepage field distribution model around the tunnel, analyzing the evolution law of the seepage field. the water balance method and underground runoff modulus method are used to predict tunnel water inflow. High density urban tunnel engineering produces strong spatial seepage and stability interactions of newly built and existing operational tunnels, which is critical to the safety and resilience of transport infrastructure. The following four basic types of boundary conditions are available in feflow. all of them can be used as time constant or in combination with a time series. the application of all the boundary conditions can be constrained by additional physical constraints. Feflow is a groundwater flow modelling software package that can be used to model the flow and transport of groundwater and dissolved material in subsurface. feflow can use shapefiles exported from geological information systems (gis) to create the modelling domain.
