A New Unified Solution for Deep Tunnels in Water-Rich Areas considering Pore Water Pressure
Geofluids, 2021 Pore water pressure has an important influence on the stresses and deformation of the surrounding rock of deep tunnels in water-rich areas. In this study, a mechanical model for deep tunnels subjected to a nonuniform stress field in water-rich areas is ...

Seismicity models based on Coulomb stress calculations
, 2010 Our fundamental, physical, understanding of earthquake generation is that stress-build-up leads to earthquakes within the brittle crust rupturing mainly pre-existing crustal faults.While absolute stresses are difficult to estimate, the stress changes induced by earthquakes can be calculated, and these have been shown to effect the location and timing ...

Study on Coulomb Stress Triggering of the April 2015 M7.8 Nepal Earthquake Sequence
International Journal of Geophysics, 2016 In April 2015, a M7.8 earthquake occurred less than one month before a M7.3 earthquake near Kodari, Nepal. The Nepal earthquake sequences also include four larger (M > 6) aftershocks. To reveal the interrelation between the main shock and the aftershocks,

InSAR观测与小震分布联合分析2021年云南漾濞MS6.4地震应力卸载对周围区域的影响
Dizhen xuebao, 2023 为分析2021年5月21日云南省漾濞MS6.4地震后震区应力变化对周围断层的影响，本文通过InSAR技术获得了漾濞地震的同震形变场，并联合小震分布数据建立断层破裂滑动模型，继而通过计算断层面上的同震库仑应力来评估此次地震对周边断层的影响，以便有效地分析地震破裂的时空解析度。结果显示：① 在升降轨InSAR数据获得的精细同震形变场中，升轨最大视线向形变量约为5.00 cm，降轨最大视线向形变量约为7.80 cm；② 余震精定位的主震震中为（99.89°E，25.67°N），震源深度为13.29 km ...

Onto what planes should Coulomb stress perturbations be resolved? [PDF]
Journal of Geophysical Research: Solid Earth, 2005 Coulomb stress maps are produced by computing the tensorial stress perturbation due to an earthquake rupture and resolving this tensor onto planes of a particular orientation. It is often assumed that aftershock fault planes are “optimally oriented”; in other words, the regional stress and coseismic stress change are used to compute the orientation of ...

Coulomb stress accumulation along the San Andreas Fault system [PDF]
Journal of Geophysical Research: Solid Earth, 2003 Stress accumulation rates along the primary segments of the San Andreas Fault system are computed using a three‐dimensional (3‐D) elastic half‐space model with realistic fault geometry. The model is developed in the Fourier domain by solving for the response of an elastic half‐space due to a point vector body force and analytically integrating the ...
