Expansion of the Minera Escondida copper mine included constructing a corrugated steel structural plate arch tunnel. The tunnel acts as a buried bridge to carry a haul road over the mine’s conveyor system. During construction of the...
A conveyor belt runs along one of the canyon benches at the copper mine. The upper slope of the canyon was undergoing a slow and predictable landslide transverse to the conveyor belt. To protect the conveyor belt from falling debris due to the...
The Crystal River Nuclear Power Plant, Unit 3, is part of a 4,700 acre energy complex that contains a 914 MW pressurized water reactor. When the client planned rigging operations for replacement of a steam generator at Unit 3, they required an...
The state of U.S. infrastructure and need for funding to improve it has been highlighted through efforts of national engineering organizations such as the American Society of Civil Engineers’ Infrastructure Report Card and the American...
Abstract: PressureCast Steel Pipe (PCSP) utilizes a patented manufacturing process to pre-compress the concrete (or mortar) lining in the steel pipe, thus making the liner less susceptible to cracking and substantially increasing the stiffness of...
Abstract: The finite-element model we propose to analyze the dynamics of accidental drop loads on critical buried structures during steam generator replacement includes representation of drop objects, impacted structures, soil media through which...
Abstract: This paper presents the results of analysis and evaluation of the seismic soil strains resulting from wave propagation or permanent ground deformation on sweeping bends in buried pipelines with bell and spigot joints. A finite element...
Engineers provide the best service to their clients by optimizing the cost of projects without affecting the quality or performance. Since buried pipe performance is the result of interaction of both the pipe and the surrounding soil embedment,...
