Mastering risks during mechanized excavation in urban centers with highly complex ground conditions

For cities, federal states and nations, future readiness is closely linked with the creation of modern and efficient infrastructure that needs to be put underground more and more often due to the lack of space. Road, subway, supply and disposal tunnel systems need to be installed underground right where they are actually required. This involves innovative solutions for tunneling projects with a high level of difficulty in terms of construction, e.g. the feasibility of large inner-city tunnels in heterogeneous grounds with high water pressures. Repeatedly mechanized excavation moves into new dimensions regarding size, length, complexity of the ground conditions and depth of underground constructions. Here the feasibility of conventional tunneling is limited. How limits can be overcome with state-of-the-art tunneling technology is clearly illustrated by a large number of international tunneling projects that have already been completed or that are currently being carried out. The focus of this presentation is on mastering risks regarding diameter-size records as well as innovative security and logistics solutions.
