Soft Ground Tunneling of the Greenbelt Tunnels
Mergentime/Loram's contract for the construction of Section E-1d Greenbelt Route Tunnels includes construction of dual 1,770-foot tunnels in soft ground, a crossover structure,...
Construction of Mt. Baker Ridge Tunnel
Mt. Baker Ridge Tunnel is a large diameter soft ground highway tunnel constructed through sensitive over-consolidated silts and clays. Its large diameter necessitates the construction...
Torsional Simple Shear Apparatus for Drained and Undrained Cyclic Testing
Since a cyclic triaxial compression apparatus was first used to study liquefaction of saturated sandy soil, many different types of cyclic shear devices have been used to investigate drained...
Small Strain Measurements Using Triaxial Apparatus
This paper presents a detailed testing methodology which can be used to determine the cyclic properties of soils at very small strains using triaxial apparatus. A discussion of specific...
Construction of Foz do Areia Dam
The methods and equipment for the construction of Foz do Areia Dam during 1976-1980 in Brazil are described. Special emphasis is given to the rockfill construction. Foz do Areia was the...
Construction of Concrete Face Rockfill Dams
The Hydro-Electric Commission, Tasmania, Australia has been building concrete face rockfill dams since 1968. Eight dams from 26m to 110m high have been completed, and the highest at 122m...
A Summary of the Seismic Qualification Utilities Group (SQUG) Program
In December of 1980, the Nuclear Regulatory Commission (NRC) initiated Unresolved Safety Issue (USI) A-46 to address the question of the seismic adequacy of equipment in 49 operating nuclear...
