Pipe Impact on Concrete Slabs
A series of pipe impact on concrete slab tests have been performed at the CEA's Cadarache Laboratory using the AQUITAINE II facility. The testing program was jointly sponsored...
The Response of Steel Containment Models to Internal Pressurization
To obtain insight and data on the response of containment vessels subjected to beyond design basis accidents, four 1/32 scale steel containment models have been subjected to internal overpressurization,...
Bayesian Procedure for Evaluation of Containment Capability
The functional requirements of a steel or concrete containment is to maintain the structural integrity as well as the leak-tight integrity of its pressure boundary under specified design...
Determination of Containment Vessel Ultimate Capacity Using Nonlinear Finite Element Analysis
Analysis of steel containment vessels is normally performed using linear elastic solutions with allowable stresses specified by applicable design codes. This method gives little indication...
Allen-McColloch Pipeline Computer Based Control System
The Allen McColloch Pipeline (AMP) was designed to deliver 416 cfs of treated water from the Metropolitan Water District of Southern California's Diemer Water Treatment Plant...
Pipeline Hydraulic Transient and Leak Detection Analysis
Liquid and gas pipelines cannot be properly designed with consideration of steady flow analysis techniques alone due to the possibility of pipeline failure resulting from uncontrolled...
Design of Thin Wall Reinforced Concrete Pipe Using Dimension Ratio (DR)
Dimension Ratio is defined as the ratio of the internal pipe diameter to the pipe wall thickness. The Caltrans culvert research leading to the development and use of the Dimension Ratio...
Residual Stresses in Piles and the Wave Equation
A data base of 18 vertical load tests on driven piles in sand is presented. On average the residual point load was 56% of the measured point load and the residual friction load 19% of...
A Flat-Dilatometer Study of Lateral Soil Response
The effect of flat dilatometer penetration on the lateral stress conditions in soil around the dilatometer blade and the soil response against dilatometer diaphragm deflection were investigated...
Consolidation Performance of Soft Clays: Part 2. Predictions
The simplified version of the model described in Part 1 was used to predict the short-term performance of the St. Alban test fill. The long-term predictive capability of the model was...
Consolidation by Sand Drain in Anisotropic Ground
The author reduces Biot's equations of consolidation into a single governing equation with the excess pore water pressure as the only unknown function and derives the theory...
Yield Behaviour and Consolidation. I: Pore Pressure Response
This paper discusses the frequency of occurrence of anomalous consolidation behaviour. The behaviour of soft clay is discussed briefly in terms of the effective stress path/yield envelope...
Time and Stress Dependent Compression in Soft Sediments
Results are presented for laboratory experiments using a typical estuarine mud settling from a slurry in columns of 100mm diameter. Measurements have been made of density and pore water...
Instrumentation Performance in Soft Clay Soils (A Case History)
In 1978, IDEAL BASIC INDUSTRIES, INC. initiated construction of a cement manufacturing plant located south of Mobile, Alabama on the Theodore Ship Channel. Because deltaic clays were too...
Waste Phosphatic Clay Disposal in Mine Cutsr
Research was undertaken to assess the applicability of waste clay disposal back into phosphate mine cuts. The pit was monitored for two years with measurements of clay surface elevation,...
New Tools Help Find Flaws
Certain electromagnetic tools for nondestructive evaluation of existing infrastructure, though not widely used, can cut cost and time of identifying flaws in existing infrastructure. Five...
Grouting Rehabs Earth Dam
To accommodate increased storage needs the Pennsylvania Power & Light Company had to reactivate a fly ash basin and raise an adjacent embankment dam. However, seepage through the...
Wetlands Development in Moderate Wave-Energy Climates
For the last three years springs of Spartina alterniflora have been planted on portions of Theodore Island, a dredged material island in Mobile Bay, Alabama. The purpose of the planting...
Draghead Designs vs. Production
This paper discusses the development and design of draghead configurations for silt materials and describes a testing program designed to determine the most efficient range of the controllable...
Acoustic Silt Density Measurement
Significant savings can be achieved on the costs of operations for the deepening and maintenance of navigation channels and harbor basins in muddy areas provided that computations are...
