A small model earth pressure balance (EPB) tunnel boring machine (TBM) will be designed that can simulate excavation similar to real on site tunneling. Monitoring will be done using acoustic emission (AE), borehole extensometer, strain gages and accelerometers will be installed in TBM and on the cubical specimen. The critical conclusions and correlation developed from the experimental results will contribute significantly and will be give better insight into the problem of tunnel squeezing.]]> Fri, 16 Feb 2018 19:26:13 GMT https://rip.trb.org/View/1500818 Incorporating Mobile Technology into the GPS/Web-GIS Method for Travel Survey and Research https://rip.trb.org/View/1236083 Thu, 03 Jan 2013 15:40:44 GMT https://rip.trb.org/View/1236083
