Abstract
A design method is developed for determining the size and strength of stabilized soil zones around tunnels for effective ground control during construction. The method is based on results of a multiphased research program that included laboratory tests of grouted soils, development of a comprehensive finite-element program for the analysis of shallow tunnels, conducting over a hundred finite-element parametric studies of stabilized tunnel problems, and collecting available case history data. Analyses show that where the stabilized zone surrounds the tunnel, it absorbs stress changes by acting as a compression ring and minimizes stress in the ungrouted soil. Where ungroutable soft layers disrupt the continuity of the stabilized zone, the structural action of the stabilized zone cannot be mobilized, but grouting still serves to prevent ground runs. Ungroutable layers have less detrimental effects if located below the springline.
