The River Walks of San Antonio Move to Providence
At the historic heart of Providence, Rhode Island, three rivers divide the city into three areas. Nearly one mile of river corridors have been abused over the last century, resulting in...
Recent Developments in Structural Optimization
This publication contains seven papers that emphasize the recent findings of mathematical formulations, numerical results, and algorithms in structural optimization. Among them, two deal...
Soil Nailing a Wall
Soil nailing is the reinforced-earth idea (in which the earth must be backfilled behind the wall) applied to cut situations. Soil nails are an inexpensive post-tensioned tieback, consisting...
CPM Harnesses Mammoth Powerplant Job
One of the largest air quality control retrofit projects in the U. S. is at the Sammis Plant of Ohio Edison Co., along the Ohio River 40 miles west of Pittsburgh. The coal-fired plant's...
Ground Freezing for Construction
For almost a century, freezing has been used successfully as an art to stabilize ground and control groundwater. First employed by the mining industry in Europe, it has since been widely...
