Expansive soil is prone to shrinkage and cracking during the drying process, leading strength permeability problems that exist widely in water conservancy projects geotechnical engineering, including foundation pits cracks at bottom of channels slopes. Such are closely related tensile soil. In this study, Nanyang expansive taken as research object radial splitting tests were performed using a p...

Subshifts are sets of configurations over an infinite grid defined by a set of forbidden patterns. In this thesis, we study two-dimensional subshifts of finite type (2D SFTs), where the underlying grid is Z and the set of forbidden patterns is finite. We are mainly interested in the interplay between the computational power of 2D SFTs and their geometry, examined through the concept of expansiv...
