Deformation Characteristics of Cohesionless Soils from In Situ Tests
This paper is a summary of seven years experience gained by the National Electricity Board of Italy (ENEL), ISMES and Technological University of Turin in assessing these parameters using...

Field Permeability Test for Earthen Liners
A sealed double-ring infiltrometer (SDRI) was developed for in-situ measurements of the hydraulic conductivity of earthen liners and covers. The characteristic of the SDRI that distinguishes...

Pressuremeter Correlations for Preconsolidated Clay
Conventional triaxial compression and consolidation tests are often utilized to obtain parameters for design of foundations. More recently, Menard pressuremeter test results have been...

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...

Flat Dilatometer Tests in Calibration Chambers
This paper presents the results of a series of Flat Marchetti's Dilatometer Tests (DMT's) performed in a large Calibration Chamber (CC) on dry Ticino (TS) and...

Residual Soil Settlement From Pressuremeter Moduli
The Menard pressuremeter test is briefly described, and practical drilling techniques are summarized for Piedmont residual soils. Applications and limitations of the pressuremeter are...

Laboratory and Field Evaluation of Cone Penetrometers
Cone penetrometers from 8 organizations have been studied by performing laboratory tests and field tests. The testing show that pore pressure and temperature zero shift affect significantly...

In Situ Tests with K_o 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...

High Quality Sampling and In Situ Testing for Deep Water Geotechnical Site Investigation
This paper discusses methods that have been used to conduct geotechnical investigations in water depths up to 2500 feet. Investigations can be conducted from supply boats, geotechnical...

Bearing Capacity of Footings on Clay CPT Method
A method is proposed to predict the ultimate bearing pressure for footings on clay using data from cone penetration tests. This method relates the ratio of ultimate soil bearing for a...

Use of Piezometer Cone Data
The piezometer cone is generally regarded as the most efficient tool for stratigraphic logging of soft soils. A thin pore pressure element (5 mm thick) can sense layers a few centimeters...

CPT Indexing of In Situ OCR in Clays
Cone penetration tests may be used to index the in situ preconsolidation pressure in clay deposits. A specified relationship between C//u/ sigma //vo and the overconsolidation ratio (OCR)...

Ports '86
Ports '86 had the theme of Innovations in Port Engineering and Development with keynote speakers looking ahead to Port Development in the 1990's. The program...

Clay Liner Hydraulic Conductivity: Comparison of Field & Laboratory Tests
Clay liner hydraulic conductivities at three hazardous waste landfill cells in Oklahoma and Utah were measured in the laboratory and in the field during construction. Prior to construction...

Clay Liner/Leachate Compatibility Modeling
Over the past several years, the results of many laboratory studies assessing the effect of various combinations of organic and inorganic chemical mixtures on the hydraulic conductivity...

Landslide-Generated Wave Studies
A serious safety of dams problem is associated with large masses of rock and debris plunging into lakes and causing damaging water waves. This concern prompted the Bureau of Reclamation...

Sea Level Rise and Coastal Stormwater Drainage
Global sea level rise as a result of the greenhouse effect and the past trend and future projection on the rise are discussed. Potential problems associated with coastal stormwater drainage...

Saltwater Intrusion in a Highly Transmissive Unconfined Aquifer
Saltwater intrusion is particularly dynamic in coastal Dade County because of the high permeability of the Biscayne aquifer, because of the good interconnection between canals and the...
