Lateral Analysis of Drilled Piers Incorporating Soil Variability
In probabilistic studies, the mean or expected value of the parameter in question, along with its measured dispersion or standard deviation, are determined. In this study the Three Point...
Markov Chains & Soil Constitutive Modeling
The focus of this research effort is the construction of a mathematical framework to assist in understanding the role of uncertainties in the constitutive/dynamic behavior of soils. The...
Application of Bayesian Methods to a Geotechnical Site Investigation in Mississippi
In 1981, the Army Corps of Engineers constructed an ammunition storage area at Bay St. Louis, Mississippi. This storage area is part of the Mississippi Army Ammunition Plant (MSAAP). Prior...
Pore Pressure Development: Probability Analysis
The development and subsequent dissipation of excess pore pressure, p in a soil deposit subject to an external load is examined using probability concepts that account for uncertainties...
Probabilistic Slope Stability?Case Study
The stability of a slope depends upon highly variable conditions of varying degrees of importance. Probability theory is used herein to assess the relative importance of the soil parameters...
Probabilistic Model for Stability of Slopes
Presented herein is a probabilistic model based on derived distributions to predict shear strength of soils and the safety factor of slopes considering uncertain properties of soil, namely:...
Reliability of Geotechnical Systems Considering Geological Anomaly
Anomaly statistics at a given site are first assessed through Bayesian methodology on the basis of site exploration data. Several methods may be then used to incorporate the anomaly uncertainties...
A Probabilistic 3-D Short-Term Slope Stability Model
A probabilistic model to analyze the three-dimensional stability of earth slopes under short-term conditions is presented. An actual failure case is studied to show the implementation...
Dynamic Maps for Seismic Risk Reduction and Effects of Soil Conditions
In order to perform useful vulnerability and risk evaluations, it is essential to have at one's disposal an automatic procedure of elaboration which provides answers in real time as soon...
Effect of Spatial Variation of Ground Motions on Bridges
The effect of spatial variation of ground motions on the response of a two-span bridge is presented. Perfectly and partially correlated earthquake ground motions are used as input motions...
Vacuum Sewers: Fundamentals and Design Methods
Vacuum sewer (VS) systems have important advantages over conventional gravity sanitary sewers or septic tank-soil absorption systems when one or more of the following conditions hold:...
Movement of Chloride Ions in a Saturated Soil Sample
A series of laboratory experiments were performed to demonstrate and track the migration of chloride ions in saturated soil samples undergoing freezing. Results from these experiments...
Rolling Incinerators
The Illinois Environmental Protection Agency (IEPA) is using a mobile incinerator to clean up a former oil and solvent storage/transfer operation which was badly contaminated. The benefits...
Biological Treatment of Hazardous Wastes
Biological treatment�using nature's bacteria and fungi�sometimes costs as little as 10-20% as incineration. Wastes in any form�solid, aqueous and gaseous�can be treated biologically....
Dilatometers Settle In
The benefits of the dilatometer test DMT are described. This geotechnical in situ testing tool was developed and patented by an Italian professor and engineer named Silvano Marchetti....
Soil Parameters for Design of Buried Pipelines
This paper presents the table of recommended design parameters for soil, shows their physical significance, and compares the resulting stiffness and strength for the variety of soil and...
New Installation Designs for Buried Concrete Pipe
The rational development of new installation designs for buried concrete pipe is described. Over 100 analyses were performed using a new computer program named SPIDA (Soil Pipe Interaction...
Design of Ductile Iron Pipe Systems
To ensure a reliable, low maintenance infrastructure capable of withstanding the test of time, proper initial design is essential. The basis of the design standard for ductile iron pipe...
Underground Storage Tank Program and Its Implications
National concern over leaking underground tanks storing hazardous materials and wastes has resulted in the implementation of the 1984 Amendments of RCRA, which include the requirement...
Monitoring the Effects of the Pipe Insertion Machine Technique
The results of an experimental study of the pipe insertion machine are presented in this paper. Strains induced in an adjacent pipeline, soil displacement, pipe deflection and vibrations...
