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...
Landslide Investigations Using the Weight Penetrometer
The weight penetrometer is a light weight device and can be easily deployed on slopes not accessible to conventional exploratory tools such as drill rigs or cone penetrometers. The weight...
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...
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 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...
Effctive Stress Interpretation of In-situ Tests
Significant differences in terms of load-settlement curves obtained from Plate Load Tests (PLT) and q//c profiles obtained from Static Cone Penetration Tests (SCPT) at two sites with different...
In Situ Tests for Foundation Vibrations
There are several well established methods of determining shear modulus in situ and these are summarized in this paper. New techniques are being developed for in situ determination of...
North American Standard Penetration Test Practice: An Essay
The Standard Penetration Test (SPT) is the in situ mechanical soil test most used by North American geotechnical practitioners. The equipment and procedures of the test have periodically...
Lateral Stress Measurement During Cone Penetration
A lateral stress sensing cone penetrometer (LSSCP) was designed and fabricated. Based on the results of calibration chamber tests in sand, relationships between measured lateral stress,...
Dilatometer to Compute Foundation Settlement
Sixteen examples demonstrate how the S. Marchetti dilatometer test (DMT) provides soil compressibility data for the rapid calculation of foundation settlements with an average ratio of...
Effect of the Fluid Velocity on the Biofilm Development
In order to get basic information concerning the application of a biological treatment to the ammonia nitrogen removal from drinking water, we considered the relation between the biofilm...
Physical Habitat Simulation and the Moveable Bed
One objective of an instream flow analysis is to quantify a flow that will maintain the existing channel and/or flush fine material from the bed. Five empirical approaches to determine...
Case Studies in Upgrading of Wood Trusses and a Heavy Timber Building
Three case studies in upgrading and rehabilitation of wood structures are presented. One case study relates to three 30m (100ft) span bowstring trusses that had to be cut at various span...
Rapid Assessment of Seismic Vulnerability
The choice of a seismic damage assessment method depends fundamentally on how the assessment will be used, but always involves definition of the expected ground motion and the structure...
ATC Methodology and Data for Rapid Assessment of Seismic Vulnerability
