Analysis of Subsidence Trough
The analysis of subsidence trough consists of several sequential steps:
- Determination of the maximum settlement and dimensions of subsidence trough for individual excavations
- Analysis of the shape of subsidence trough
- Back calculation of the shape and dimensions of subsidence trough providing it is calculated at a given depth below the terrain surface
- Determination of the overall shape of subsidence trough for more excavations
- Post-processing of other variables (horizontal deformation, slope)
The analysis of maximum settlement and dimensions of subsidence trough can be carried out using either the theory of volume loss or the classic theories (Peck, Fazekas, Limanov).
