A correlation study between the fracability and brittleness of shale gas reservoir is crucial for optimize reservoir reconstruction and enhance shale gas recovery. To investigate the relationship between fracability and brittleness of shale, a series of uniaxial compression tests of Silurian Longmaxi shale samples were carried out using a novel setup that combines X-ray micro-computed tomography with a uniaxial loading apparatus. Based on the CT images obtained from the test, fractal dimension o...

An understanding of crack propagation is critical for the development of rock mechanic models. To study the propagation of internal cracks in situ and determine their formation mechanism, a series of uniaxial compression tests on shale specimens were conducted using a novel setup that combines X-ray micro-computed tomography (X-ray micro-CT) with a uniaxial loading apparatus, which allows CT scans to be performed during compression. Macro- and micro-scale internal cracks were extracted from CT i...

Abstract Better understanding the evolutionary mechanism of landslides is very important to predict their occurrence based on firm scientific grounds. The stability of a rock slope is often dominated by one or more locked segments along a potential slip surface with a large bearing capacity to resist instability. We propose three preliminary categories for locked segments and develop a physical model for predicting the instability of rock slopes with locked segments, by coupling a one-dimensiona...

Applying the statistical damage theory based on the Weibull distribution to describe rock deformation and failure processes is an important development in rock mechanics. The shape parameter of the Weibull distribution, m, determines the basic shape of the distribution curve; additionally, it also represents a physical characteristic which can be applied when constructing rock constitutive models. To study the evolution of m during rock failure when applying the Weibull distribution to rock mech...

It is clear that evaluating the fracturing effect with laboratory tests can shed some light on designing fracturing programs for shale gas exploitation. To evaluate the fracturing effect quantitatively, a series of uniaxial cyclic loading tests on shale were conducted. Based on the experimental results, a damage variable derived from the total axial strains of the loading–unloading cycles was established and introduced into a damage evolution equation to analyze damage evolution in the shale. In...
