Theme: Slope Stability evaluation taking strata formation and tectonic stress into consideratio
Procedure:
1. Hydraulic stress measurement is carried out at a underground site
2. Local stress state at the site is determined from hydrofracturing date
3. Tectonic stress state is evaluated taking strata boundary, two kind of strata properties and topography into consideration from local stress state by 3D BEM
4. Slope stability is investigated taking the tectonic stresses evaluated into consideration by 3D BEM
Division into BEM elements
(a)
FSM elements on the surface boundary
(b)
DDM Joint elements along the formation boundary (a part of them is disclosed by removing some of the surface elements)
FSM: Fictitious Stress Method
DDM: Displacement Discontinuity Method
