关键词：Hydrogen sulfide in underground hydrogen storage sites Implication of thermochemical sulfate reduction
摘要：AbstractHydrogen is recognized as a clean energy carrier that can decarbonize heavy industry and the aviation system. However, the infrastructure is not yet ready for a hydrogen economy and large-scale hydrogen storage is needed to balance the mismatch between supply and demand. Therefore, depleted gas fields have been proposed as suitable storage sites, given the presence of infrastructure and...

关键词：An analytical solution of direction evolution crack growth during progressive failure in brittle rocks
摘要：AbstractMicrocrack growth during progressive compressive failure in brittle rocks strongly influences the safety of deep underground engineering. The external shear stress τxy on brittle rocks greatly affects microcrack growth and progressive failure. However, the theoretical mechanism of the growth direction evolution of the newly generated wing crack during progressive failure has rarely bee...

关键词：A comprehensive study on in situ stress field characteristics and changes rock mechanical properties deep mines northeastern Yunnan China
摘要：AbstractThe Maoping lead–zinc mining area is a significant metal mine site in northeastern Yunnan. In this study, both hydraulic fracturing in situ stress testing and ultrasonic imaging logging were first carried out in the mining area. Second, 930 focal mechanism solutions and 231 sets of stress data near the mining area were collected. Then, the variations in the type of in situ stress field...

关键词：Seismic performance of concrete tunnelsandpile interaction by the shake table test
摘要：AbstractThis research presents the square root sum of squares response of displacements and tunnel moments under the Kobe and Loma Prieta seismic excitations with a peak ground acceleration of 0.05 g for various dry relative densities of local sand in Bangladesh. For this reason, a one-dimensional gravitational shake table test was performed after calibration to determine the seismic performan...
