摘要
Abstract
Based on the early high strength performance advantages of nano-crystalline gel polymer shotcrete,this paper explores the superiority of early high-strength shotcrete in controlling deformation of Class Ⅳslate tunnel surrounding rock through a research approach combining indoor experiments with discrete element numerical simulation.The results show that under the conditions of high horizontal stress and high dead weight stress,the early and high-strength shotcrete used in tunnel excavation support can control the deformation of surrounding rock well and early,and the support significantly reduces the ultimate excavation deformation of surrounding rock,and the damage of-shotcrete supporting layer of surrounding rock is significantly reduced.关键词
