SHALLOW URBAN TUNNELLING THROUGH HETEROGENEOUS ROCKMASSES: PRACTICAL EXPERIENCE FROM SMALL SCALE TUNNELS IN CALGARY, ALBERTA AND THE INFLUENCE OF ROCKMASS LAYERING ON EXCAVATION STABILITY AND SUPPORT DESIGN
Shallow excavations through variable rockmasses in urban centers present significant design challenges, whether considering small diameter tunnels for utilities or large span underground caverns. In designing shallow excavations in urban environs, it is especially critical to minimize the impact of...
