Foundation Studies in a Fault Zone and a Steep Valley Slope
This paper presents two case histories which illustrate unique problems in defining the character of rock for support of structures. The first case study concerns a conventional building...
Soil-Rock Transition Zone: Uncertainties for Design and Construction
This paper addresses the problem of establishing definitions of the soil-rock boundary with regard to different engineering applications in the Piedmont geologic provinces. Three engineering...
Rock in the Limestone Regions of the Southeastern United States
Problems often arise in the shaft drilling industry in the Southeast. The karst areas in this region have certain situations found in few other places. Erratic boulders and limestone pinnacles...
Design of Substation Foundations for Liquefaction
When substation foundations penetrate liquefiable strata within risk prone seismic regions, the potential loss of support must be evaluated with state-of-the-art methods to determine foundation...
Lateral Load Test on Driven Pile Footings
The October 17, 1989 Loma Prieta earthquake provided an ideal time and situation to perform for the first time, at no installation cost, a full scale lateral load test on a group of driven...
Identify the Marina User Market and Make the Customer a Part of the Planning Team: Designing and Managing for the User's Needs
A practical surveying method is described which allows a marketing firm to simultaneously - and quantitatively - analyze demographic market composition (for both upland and in-water uses)...
The Application of a Structural Analysis Program to Floating Dock and Guide Pile Design
The floating dock systems and guide piles used in marinas are often designed using over simplified analysis techniques. However, if the dock system is flexible or if either the soil conditions...
Frictional Base Isolation Using a Layered Soil-Synthetic Liner System
The application of smooth geotextile liner materials to seismic base isolation of shallow foundations has been evaluated using laboratory testing and numerical analysis. Laboratory testing...
Dam Foundation Grouting
Response Surface Fitting in Offshore Structural Design
Failure probability estimation of complex offshore structures requires the modeling of the system behavior in terms of all uncertain parameters. This paper investigates the applicability...
Stochastic Behavior of Concrete Arch Dam-Reservoir Fluid-Foundation Systems in Nonstationary Random Vibration
The behavior of elastic arch dam reservoir fluid system subjected to ground acceleration excitations has been studied extensively by Chopra and his colleagues. In their studies, the excitations...
Reliability-Based Design Requirements for Foundations of Buildings Subjected to Earthquake
Optimum seismic design coefficients and safety factors with respect to shear and overturning failure modes are obtained for a set of multi-story frame buildings idealized as single-mass...
Reliability-Based Analysis of Shallow Foundations
The effects of different parameters on the reliability of shallow foundations are examined. It is found that the footing depth, the footing length, and the load ratio have almost no effect...
One Power Plant, Two Job Sites
In response to the lingering questions about energy, officials from Vidalia, La initiated a plan in 1977 to build a hydroelectric plant at a site 90 mi northwest of Baton Rouge, where...
Uprating an In-Service Offshore Pipeline
The Ekofisk to Emden 36-inch pipeline, transmits gas 275 miles from the Ekofisk field to Emden, West Germany, and has been in operation since 1977. The operator Phillips Petroleum Company...
Geometrical Nonlinearity in Offshore Pipelines
Pipelines are very flexible structural systems which are subjected to various boundary conditions. For instance, during the laying process, the pipes roll on the guidance tracks on the...
Seam Examination
Charron discusses the importance of seam sampling in geomenbrane installation. In 1988, about 30 million mi of polyethylene geomembranes were used to line landfills, liquid impoundments,...
Twin Pipeline Crossing of the Fraser River
A new creek water supply was developed for the communities of Mission and Matsqui, British Columbia, Canada, in the early eighties. Over 60 kilometres of 450 mm to 900 mm diameter ductile...
Restoration of a Buttress Dam
Inspections of Morris Shepard Dam on the Brazos River in Texas revealed serious defects in the dam and its foundation. Piezometric pressures below the spillway buttresses greatly exceeded...
Morris Sheppard Dam: A Rational Approach to Stability Analysis
This paper details the excessive foundation piezometric conditions found during a routine five-year inspection, and presents the results of backfigured stability analysis of a critical...
