Measurement and Modelling of Geotechnical Structures II
- Michal Šejnoha (guarantor)
- Department of Mechanics
The course is devoted to the modeling of time-dependent problems in geomechanics. Advanced laboratory measurements in gallery Josef will be accompanied by numerical modeling using the finite element method. The course covers 4 different topics: (i) Heat transport, (ii) Steady state ground water flow, (iii) Transient ground water flow, (iv) Coupled mechanical and ground water flow in fully saturated deformable soil body – consolidation. Numerical modeling will be performed employing the GEO5 FEM and SIFEL software packages.
Topics covered in individual lectures:
1-4 weeks: One-day course on measurements of transport parameters – gallery Josef. Laboratory measurements in permeameter, measurement of the coefficient of thermal conductivity and thermal capacity on a rock sample. Setting up in situ experiment and measurements kick off. The measured data will be collected and gradually evaluated throughout the whole semester.
5-7 weeks: Modeling of heat transport – theoretical formulation of stationary and nonstationary heat transport, boundary conditions, FEM formulation, methods to solve nonstationary transport problem (time integration), modeling a selected task using FEM (program SIFEL).
8-10 weeks: Modeling of ground water flow – theoretical formulation of stationary and nonstationary ground water flow, Darcy law, continuity equation, boundary conditions, transition zone, formulation of finite elements, Modeling a selected task using FEM (program GEO 5).
11-13: Modeling consolidation – theoretical formulation of fully coupled transport of ground water in a deformable soil body assuming fully saturated soils, formulation of finite elements, Modeling a selected task using FEM (program GEO 5).
