Abstract

This paper describes the sub-surface ground movements caused by multiple tunnel constructions in soft ground using a small-scale (1:50) laboratory facility. The test facility consists of a 1800 mm long by 600 mm wide by 450 mm high steel tank into which Speswhite Kaolin clay is consolidated from a slurry. An augering technique was used to construct parallel 80 mm diameter tunnels in the clay at spacings ranging from 1 to 4 tunnel diameters. The apparatus and the laboratory testing are described, and some preliminary results presented which are compared to traditional semi-empirical theories for predicting the ground movements above full-scale tunnels.
