Correlation of reservoir and earthquake by multi temporal-spatial scale flow driven pore-network crack model in parallel CPU and GPU platform

Abstract

Coulomb failure assumptions. Jaeger and Cook (Fundamentals of rock mechanics. Methuen, New York, 1969) is used to evaluate the earthquake trigger, and pore pressure (Biot, J Appl Phys 12:155, 1941; 26:182, 1955; 78:91, 1956; J Geophys Res 78:4924, 1973) parts reflect the effect of reservoir which closed to the earthquake slip. Fluid flow driven pore-network crack model (Zhu and Shi, Theor Appl Fract Mech 53:9, 2010) is use to study the reservoir and earthquake. Based on the parallel CPU computation and GPU visualization technology, the relationship between the water-drainage sluice process of the Zipingpu reservoir, stress triggers and shadows of 2008 Wenchuan Ms 8.0 earthquake and porosity variability of Longmenshan slip zone have been analyzed and the flow-solid coupled facture mechanism of Longmenshan coseismic fault slip is obtained.
