In the new tunnel under close distance through the existing tunnel risk source, the grouting scheme developed to compensate for stratum losses is still based on empirical methods, relying on the overburden thickness of existing tunnels. This can pote

An orthogonal set of experiments was performed on common shotcrete, where the coarse and fine aggregates were substituted with ceramsite and pottery sand, while basalt and plant fibers were also added. The influence of ceramsite, pottery sand, basalt

During the construction of water-rich bored tunnels, it is important to improve the impermeability of the primary support shotcrete to ensure construction safety. This work considers the underground excavation of water-rich strata in the section betw
