Experimental study on the influence of ground temperature and pore water pressure on the mechanics of excavation unloading sandstone

Abstract As tunnel engineering in western China advances deeper underground, it encounters increasing issues of high ground temperature and high water pressure. To study the mechanical properties of unloading sandstone under the combined effects of temperature and pore water pressure, triaxial unloa...
