摘要：AbstractConventionally, foundations have been classified as shallow or deep in routine civil engineering practice. However, due to recent developments, two other approaches, semi-deep and ground modification foundations, are now available, complicating foundation categorization. Accordingly, a new concept for foundation categorization is introduced in this paper based on insights into the theor...

关键词：Slit tube responses and rock fracture characteristics in slit charge blasting under high situ stress
摘要：AbstractDeep mining of natural resources, like coal, is increasingly utilizing directional blasting technology with slit charge for rock blasting at greater depths. This study, based on numerical simulation methods, analyzes the dynamic behavior of slit charge blasting in three aspects: slit tube dynamic response, hoop stress evolution, and crack propagation. According to research findings, the...

关键词：Stress analysis of crack characteristic anthracite under dynamic loading
摘要：AbstractThe coal dynamic characteristic stress identification under dynamic load is important for guiding underground mineral mining and predicting underground dynamic disasters. In this article, the dynamic compression test of anthracite under five strain rates is carried out, the evolution law of three kinds of crack characteristic stress is analyzed, and a prediction model of the crack chara...

关键词：A novel construction approach for the pore structure model principally focuses on controllable roundness of rock particles
摘要：AbstractPores among particles provide the main space for the storage and migration of deep underground fluids (such as oil, gas, groundwater, and unconventional natural gas). The pores form a pore structure with complex morphology which is mainly dominated by the shape and distribution of particles. Therefore, the reconstruction of the pore structure or granular porous media and the evaluation ...

关键词：Experimental and constitutive modeling investigations on marble in Jinping Underground Laboratory
摘要：AbstractThe Jinping Underground Laboratory is the deepest and largest underground laboratory in the world, with a maximum buried depth of approximately 2400 m. The objective is to study the brittle-ductile transition of marble through a combination of experimental research and constitutive modeling. Triaxial compression and triaxial cyclic loading tests are initially conducted to explore the a...
