TL;DR: In this article, the authors designed a series of three-point bending tests and shear fracture tests to investigate the features of acoustic emissions (AE) signals for different modes, and the Extended Finite Element Method (XFEM) was also adopted to simulate these experiments processes.

TL;DR: To better understand the formation and evolution of hierarchical crack networks in shales, observations of microscopic damage, and crack growth were conducted using an in situ tensile apparatus inside a scanning electron microscope.

TL;DR: In this article, the influence of dip directions on the main deformation region of layered rock around tunnel was studied using a 3D distinct element code called 3DEC, and the authors found that the deformation regions around tunnels are regularly changeful along with different intersection angles between dip direction and advancing direction of the tunnel.

TL;DR: In this article, a set of quantitative comprehensive evaluation methods to analyze the karst foundations in a residential area of Tangshan, China is presented, in combination with a numerical simulation to evaluate the stability of the kartst foundations of urban high-rise buildings.
