Tunnel boring machines are excavating nearly 19 miles of tunnels 17-32 ft in diameter as part of Milwaukee's $1.9 billion upgrade of its sanitary sewage system. Laid out to...
Capacity Increase of Multi-Jet Pelton Turbines
The recent connection to the grid of large capacity thermal stations, to meet the increasing demand, has entailed an evolution in the type of services required from storage plants with...
Re-Use of Civil Structures Make Norway Hydro Possible
Utilization of abandoned civil facilities made the addition of 1,800 KW to an operating 3,200 KW hydro plant of the City of Norway, Michigan Light and Power feasible. Work consisted of...
Leakage from Pressure Tunnels and Shafts
Several issues related to leakage from unlined pressure tunnels and shafts are reviewed and discussed. They include confinement, or cover requirements relative to hydraulic jacking of...
Design of the Tunnel System for the Terror Lake Hydroelectric Project
The Terror Lake Hydroelectric Project, Kodiak, Alaska, contains a 5-mile-long (8. 1 Km) power tunnel with supplementary stream diversions entering it by two shafts along its alignment....
Synopsis: Ozark-Webbers Falls Turbine Repairs
The Ozark and Webbers Falls powerhouses were designed and constructed under the supervision of the U. S. Army Corps of Engineers and are located on the McClellan-Kerr Arkansas River Navigation...
Shear Mobilization on Laterally Loaded Shafts
From the results of a pressure cell instrumented rigid shaft embedded in stiff clay and subjected to horizontal static loading the side shear mobilization rate, and its contribution to...
Control of Thistle Lake, Utah
In April of 1983, the Thistle slide blocked the flow of the Spanish Fork River and traffic using the Denver and Rio Grande Western Railroad, U. S. Highway 89, and U. S. Highway 50 and...
Predictions of Pile Shaft Capacity With the PLS Cell
In situ measurements of stresses and pore pressures on a model pile shaft, the Piezo-Lateral Stress (PLS) cell, are utilized to reconstruct the conditions of load tests involving two large...
Dilatometer Tests for the Design of Grouted Piles in Rock
A case study of drilled and grouted piles in rock, which were analyzed using results of down-hole dilatometer tests is presented. The tests were performed from a jack-up platform in water...
Bentonitic Slurry in Constructing Drilled Piers
Bentonitic slurry is employed extensively in the construction of drilled shafts. While serious problems can occur, evidence is presented to show that the proper use of slurry will lead...
Predicted and Measured Performance of a Foundation
The predicted and measured short term foundation behavior of a 28 story building in downtown San Antonio, Texas is reported. The soil is a stiff to hard clay and clay shale. The design...
Observations on Load Tests for Drilled Shafts
This paper focuses on three specific areas pertaining to load tests for drilled shafts: 1) basic considerations and load testing procedures, 2) interpretation of uplift load test information,...
Drilled Piers and Caissons II
Drilled piers or caissons, also called drilled shafts or bored piles, have long been a very cost effective foundation solution for many soil profile and load situations. A distinct advantage...
