Summary
The course includes basic principles of geotechnical monitoring, basic principles of monitoring systems and an overview of methods and instrumentation equipment that can be used for monitoring stress in the rock or the environment. the reinforcement, reinforcement loads, deformations, subsidence, water pressure, water flow, seismic activity, radon (load cells, inclinometers, konvergometry, extensometer, piezometer, settlement of sensors, indicators of water flow, etc.). In
this course, students are also acquainted with the design of monitoring for various types of underground structures, slopes and embankments, and treatment options resulting monitoring data, including any back analysis.
