Nonlinear seepage mechanical model and bifurcation analysis for fluid-solid coupling in fractured rock mass
Henan Polytechnic University · State Administration of Work Safety
Abstract
With the development of underground engineering and oil and gas exploitation, the problem of fluid-solid interaction in fractured rock mass has become increasingly prominent, and its complex coupling mechanism has a profound impact on the stability and safety of engineering. The coupling effect between fluid and solid skeleton in fractured rock mass under the interaction of stress field and seepage field is discussed in this study. Based on the effective stress principle, the effective stress formula including porosity is constructed, and the governing formula of elastic fluid-solid coupling stress field considering the deformation of solid skeleton is developed. By introducing non-Darcy seepage formula and…
