What is Multistage Tunnel Excavation Guide about?

This document describes the modeling procedure for a multi-stage tunnel excavation project using FLAC. The modeling involves generating a grid representing the in-situ rock mass conditions, assigning material properties, and applying initial stresses. An unsupported excavation is then modeled to develop a ground reaction curve. Excavation is modeled in four stages, with installation of rockbolts after 50% load relaxation and shotcrete after 75% relaxation for each stage. The procedure involves defining mate
