Mechanics of Crack Propagation in Stiff Clays
Many stiff clays forming part of natural slopes and earth dams exist in the fissured state. When these cracks are subjected to gravity induced normal and shear stresses they may propagate....
A Laboratory Investigation of the Undrained Small Strain Behavior of London Clay
Three different total stress-paths were followed during shearing of the anisotropic consolidated (CAU) tests: compression, extension and a stress-path simulating an element under a plate...
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...
Training Programs for Engineering Consulting Firms
Engineering consulting firms heavily use and support in-house training programs. The objectives of these training programs are to: (1) supplement the graduate engineer's educational...
Flexural Behavior of Reinforced Masonry Walls and Beams
Many reinforced masonry walls and beams were tested as a part of the U. S. -Japan cooperative research program on masonry building structures. Six concrete block and two clay brick masonry...
Stress-Strain Behavior of Grouted Hollow Unit Masonry
Experimental results from axial stress-strain tests including post-peak response on hollow unit masonry prisms are compared to those of previous researchers....
Dynamic Soil-Structure Interaction for RC Lifelines
The behavior of buried cylinders merits attention because of the impact of lifeline survivability under earthquake effects, and failures may adversely affect many communities that employ...
Soil-Structure Interaction at the Waterfront
In 1981 the Naval Civil Engineering Laboratory (NCEL) undertook a review of available material models. Comparison was made between test data and model predictions. Based on this study,...
Nonlinear Response Combination in Seismic Analysis
Simple, approximate methods are developed to evaluate the maxima of response measures which are nonlinear functions of modal responses to seismic input. Examples for such response quantities...
The Simulation of Soil-Concrete Interfaces with a Non-local Constitutive Model
This investigation explores a method for predicting deformation in the vicinity of interfaces of dissimilar materials such as concrete and soil. Based upon the basic features of the deformation...
Settlement of a Reactor Containment on Sand
In this paper, predicted and observed settlements are presented for the reactor containment structure of the Beaver Valley Power Station - Unit 2, Shippingport, Pennsylvania. The Beaver...
Gabon Mineral Port Master Plan?A Case History
The integrated design of infra-structure and superstructure of marine terminals for bulk cargoes presents opportunities for innovative solutions that can produce substantial economic benefits....
Geotechnical Aspects of Stiff and Hard Clays
This publication contains articles that deal with field and laboratory measurements of engineering properties of stiff (overconsolidated) clays, and comparisons of predicted and measured...
In Situ Testing for Lock and Dam 26 Cellular Cofferdam
The in situ testing consisted of split spoon and cone penetration tests, Menard and self-boring pressuremeter tests, and Marchetti dilatometer tests. The testing program proved to be challenging...
Borehole Shear Test and Slope Stability
Three Iowa landslides analyzed on the basis of Borehole Shear Test (BST) data are reported. The soils included CL and ML loess and glacial till, and CH clay shale. Back-calculations from...
Electrical In Situ Measurements for Predicting Behavior of Soils
A new method is presented for predicting the in situ stress-strain behavior of fine grained soils based upon in situ measurements of its electrical properties. The method involves the...
Strength of Fine-Grained Soils Using the Piezocone
Evaluation has been made of several theories and methods for deducing the undrained and effective stress strength of saturated fine-grained soil from piezocone test results. Bearing capacity...
In Situ Tests with Ko Stepped Blade
The results of field tests conducted using the K//o Stepped Blade to determine lateral stresses and other geotechnical properties are presented. The sites tested represent a wide range...
Pore Pressure Effects in Borehole Shear Testing
The effects of excess pore pressures on shear strength results obtained using the Borehole Shear Test (BST) were investigated. Pore pressures were measured during the consolidation, shear,...
Electrical Method of Predicting In Situ Stress State of Normally Consolidated Clays
The electrical method was used to characterize the electrical anisotropy, shape and cementation of fine grained soils. It was found that for normally consolidated soils there is a strong...
