Trenchless Diversity Fuels Growth of Construction Activities
This paper describes a variety of trenchless technology methods of reconstructing America's decaying pipeline infrastructure by using minimum and /or 'no-dig processes'. The decay of our...

Connection of Grouted Tubular Insert Piles to Soil
Force transfer between offshore production jackets and tubular piles is effected by weld bead shear connectors, acting within the grout filled annulus between the piles and pile sleeves...

Estimation of Water-Filled and Air-Filled Porosity in the Unsaturated Zone, Yucca Mountain, Nevada
The responses of density and dielectric logs are formulated in terms if the matrix properties, air-filled porosity and water-filled porosity. Porosity values obtained from logs from borehole...

Carbon Isotopic Data from Test Hole USW UZ-1, Yucca Mountain, Nevada
Rock-CO2-gas analyses in test hole USW UZ-1 at Yucca Mountain indicate that gas movement in the unsaturated zone is likely through a dry-fracture...
