DEVELOPMENT OF DESIGN PROCEDURES FOR STABILIZED SOIL SUPPORT SYSTEMS FOR SOFT GROUND TUNNELING. VOLUME II. PRELIMINARY RESULTS

This report describes the experimental and analytical work carried out at Stanford University during the first year of a research effort devoted to the development of a rational design methodology for grouted tunnels. The long range objective of this work is to provide a designer with a simple tool which can be used to select the size, strength and stiffness of a grouted soil zone around a tunnel which will economically and effectively limit surface deformations caused by tunneling. The first year effort has been devoted to developing laboratory procedures to study load-deformation response of chemically stabilized soils, performing laboratory tests of typical stabilized soils and evaluating the observed behavior, performing load tests on soil samples grouted under field conditions, developing a finite element code which can reasonably model the effects of tunnel construction in grouted soil zones, and documenting existing field case histories and applying the new finite element code to study some of the actual tunneling cases.
