This section addresses site investigation issues that are important for detailed design and construction of microtunneling projects. These site investigations include the following: Geotechnical...
Extreme Wave-Force Calculation Procedure for 20th Edition of API RP-2A
The paper describes the revised guideline design wave force calculation procedure approved for the 20th edition of the API-RP2A WSD and the first edition of the API-RP2A LRFD and contrasts...
A Simple Model to Predict Soil Resistance to Driving for Long Piles in Deepwater Normally Consolidated Clays
As the exploration and development for offshore oil and gas reserves moves into the deepwater environment of the continental slope, a good model is necessary to evaluate drivability of...
Mechanisms Controlling the Permeability of Clays
Coefficients of permeability, calculated using Terzaghi's theory of one-dimensional consolidation, are reported for smectite, illite, and kaolinite, in water, methyl and ethyl...
Radial Flow Consolidation Testing
A radial flow consolidation cell that can be used with commercially available loading frames was developed and a series of tests were performed on samples of sedimented kaolin. Simple...
Application of Model Pile Tests to Axial Pile Design
Experiments conducted with instrumented model pile segment probes at Harvey and Empire, Louisiana are summarized and the observed behavior interpreted. Correlations are developed for the...
Reliability and Resilience � Essential Ingredients of Sustainable Geotechnics
Sustainability of a system is its ability to survive and retain its functionality over time. In very simple terms, sustainability deals with the capacities (resistances) and demands (loads)...
Offshore Technology in Civil Engineering
Hall of Fame Papers from the Early Years: Volume Seven
Prepared by the Program Committee of the Offshore Technology Conference of the Coasts, Oceans, Ports, and Rivers Institute of ASCE. This series presents...
Groundwater Flow Model Development at the Nevada Test Site
The Underground Test Area Project (UGTA) of the National Nuclear Security Administration.s Nevada Site Office is in the process of assessing and developing regulatory decision options...
Simulating Radionuclide Transport Away from an Underground Nuclear Test: Linking Non-Isothermal Flow and Mechanistic Reactive Transport
The low-yield (0.75 kiloton) Cambric underground nuclear test situated in alluvium below the water table offers unique perspectives on radionuclide transport in groundwater. The Cambric...
Transport Model Uncertainty and Sensitivity Analysis for Groundwater Releases of Radionuclides from Subsurface Nuclear Tests
Uncertainty analysis of groundwater flow and transport models is a topic of considerable interest in the groundwater modeling communities. The Underground Test Area (UGTA) Project of the...
Groundwater Transport Modeling Using Fuzzy Sets and Fuzzy Logic
Modeling of groundwater flow and transport is inherently uncertain. The predictive capability of the model depends upon both the quantity and quality of hydrogeologic data. The introduction...
Watershed Modeling for Surface-Groundwater Interaction
Groundwater use has increased rapidly due to irrigation development in the Great Plains. This is especially true in the Republican Basin that intersects the three states of Nebraska, Kansas...
Hydrologic Comparison of Four Types of Permeable Pavement and Standard Asphalt in Eastern North Carolina
A permeable pavement parking lot in eastern North Carolina consisting of four types of permeable pavement and standard asphalt was monitored from June 2006 to July 2007 for hydrologic...
Some Case Histories of Pile Foundations in Permafrost
Foundations for permafrost conditions should conform to one of three basic design principles: keep it frozen, let it thaw, or thaw the ground before construction. To keep the permafrost...
