A Preliminary Analysis of In-Situ Stress at Mount Meager by Displacement Discontinuity Method with Topography and Tectonics Considered

Geothermal energy is one of the most stable and clean solutions to replace traditional fossil fuel resource. The South Meager geothermal prospect, located in southwestern British Columbia, contains large resources due recent volcanic activities. in-situ stress state prospective area that influences characteristics fractures, thus affecting productivity, remains unknown. In this paper, we present a preliminary analysis induced by gravitational load at Mount Meager, with tectonics considered. model was constructed 3D displacement discontinuity method based on site-specific topography. reveals impact topography more prominent shallow deep regions, while an intermediate depth range. With implementation inferred tectonic state, normal faulting regime takes place (<800 m); (800–1600 m), transition from strike-slip then thrust occurs; deeper (>1800 fault type becomes again. orientations major minor horizontal stresses varying local perfectly aligned NWN-SES 330° NEE-SWW 60°, respectively, as increases.
