Abstract

In such cases of closely adjacent tunnels being bored one after another, the preceding tunnel is ill-affected by the one to be bored later. The existing standard specification, however, contains only a few statements about any precise assessment of the possible tunnel behaviors in the field, when tunnels are bored in close to proximity to one to another. This paper tries examinations about the effect of the adjacent tunnels bored, using the design models including frame models, frame models equipment with ground-spring reacting in proportion to lining displacement, and finite element models based on the field measurements.
