TL;DR: In this article, the authors proposed a thermo-hydro-mechanical coupling model considering the deformation of fractal fractures, which is regarded as a thin elastic layer existed in the bedrock, whoes deformation depends to the bedrock and its own mechanical properties.

TL;DR: In this paper, a self-designed particle transfer permeability testing system was used to test the crushed mudstones' flow properties, which included fine filling particle transfer rate, porosity increase rate and permeability under the conditions of varying pore pressure, particle size mixture and compaction level (initial porosity).

TL;DR: In this article, a variational principle was used to formulate coupled thermo-mechanical phase-field method by the variational principles to estimate the effect of thermal contribution and initial stress field on the micro-cracking behavior of shale matrix.

TL;DR: In this paper, a coupled thermal gas-mechanical (TGM) model was proposed on the basis of the elastic damage principal, and the coupling relationships were expressed by the governing equations.

TL;DR: A new forecast system, which is based on a hybrid genetic algorithm (GA) with the support vector machine (SVM) algorithm, a model structure and the related parameters are proposed simultaneously on water inrush prediction and testing results show that GA has a useful ability in finding optimal parameters of a SVM model.
