The Spring of 2011 brought heavy rainfall and snowmelt throughout the Midwest, resulting in record flow rates and flood stages on the Lower Mississippi River from Cairo, Illinois to the Gulf of Mexico. In many locations, the flood crested at levels above those ...

As with most highway bridges, railway transitions experience differential movements due to differences in track system stiffness, track damping characteristics, foundation type, ballast settlement from fouling and/or degradation, as well as fill and subgrade ...

Railway transitions experience differential movements due to differences in track system stiffness, track damping characteristics, foundation type, ballast settlement from fouling and/or degradation, as well as fill and subgrade settlement. This differential ...

Drained residual shear strength is applicable to slopes containing preexisting shear surfaces and preexisting landslides. Laboratory ring shear testing by various researchers suggest the possibility of strength gain along preexisting shear surfaces which had ...

The use of fabricated geomembranes can facilitate installation of a containment system, closure cell, final cover system, sports turf barrier, floating cover, e.g., over a leachate pond to reduce precipitation and leachate volume, pond liners, e.g., stormwater ...

Performance of four different municipal solid waste landfill liner systems, i.e., Subtitle D composite liner system, composite liner system with a geosynthetic clay liner (GCL) instead of low permeability compacted soil, Wisconsin NR500 liner system, and proposed ...

This paper presents an overview of the design guideline for the use of expanded polystyrene (EPS)-block geofoam for slope stabilization and repair applications based on the results of National Cooperative Highway Research Program (NCHRP) Project 24-11(02). ...

Back-analysis of a landslide is performed to estimate the mobilized shear strength of the problematic layer. Back-analysis can be an effective procedure for estimating the mobilized shear strength because it avoids the problems associated with laboratory and ...

Drained residual shear strength is considered applicable for the analysis of slopes with a preexisting shear surface. Torsional ring and direct shear tests were performed to investigate the gain in strength, if any, along a preexisting shear surface with time. ...

The excess pore water pressure developed in the Upper San Fernando Dam during the 1971 San Fernando Earthquake has been evaluated in several studies. Almost all of these studies indicate large excess pore pressure ratios developed only in the upstream and ...
