Effect of Loading Type on Generated Stresses around a Circular Tunnel Lining in Sand

The study is carried out to investigate the behavior of tunnel lining in sandy soil byevaluating the magnitudes of the generated stresses that are generally required to ensure thesafety of tunnel construction. The testing program comprised different factors, i.e., sanddepth, density with and without...

description The study is carried out to investigate the behavior of tunnel lining in sandy soil byevaluating the magnitudes of the generated stresses that are generally required to ensure thesafety of tunnel construction. The testing program comprised different factors, i.e., sanddepth, density with and without the effect of surface loading. The experimental work wasaccomplished through an instrumented (strain gauged) circular tunnel model. It was shownthat the generated stresses, for different loading types, i, e., surcharge, circular or striploading, decreased as the sand density increases for all regions (Crown, Shoulder & Springline)and they increase as the sand depth increases. The results are presented in the form ofdesign charts.
