Features: This book conducts a numerical simulation study on the construction method of strong pre-support for lower guide tunnels in broken surrounding rock, demonstrating that this method is beneficial to utilizing the self-supporting capacity of surrounding rock and maintaining its stability, aligning with the New Austrian Tunneling Method (NATM) principles. It also conducts systematic research on issues such as the stability of surrounding rock and the internal force distribution of support structures in single-arch and double-arch tunnels with two and three lanes, respectively.
