Stochastic Conditional Simulation of Berea Sandstone Geophysical Properties with a Counterpropagation Neural Network
The ability of a counterpropagation neural network to produce stochastic conditional simulations is applied and evaluated on a real dataset. This network functions as a nonparametric clustering...
Construction Through Crude Oil
When the Hilltop Interceptor project in Cleveland confronted oil-saturated sandstone, designers had to rethink their shaft construction and support procedures. Among the hazards were volatile...
Deformations About Excavations in Highly Stressed Rock
The central business district of Sydney, New South Wales (NSW), is dominated by the Hawkesbury Sandstone, a Triassic sedimentary formation. Measurements have confirmed the existence of...
Sandstone Materials Used as Riprap
A study was conducted to determine if sandstone materials could be potentially used as riprap. Nineteen rock samples (16 sandstone samples) were collected in six western states. The rock...
The Introduction of Steel Fibre Shotcrete to Underground Cavern Support in Taiwan
The Mingten project is located in a sheared, sandstone rock mass near a regional fault. The design philosophy introduced steel fibre shotcrete as a permanent cavern support in Taiwan....
Estimates of Permeability of Porous Materials Using Image Analysis of Cross Sections
We have developed an image processing method for characterizing the pore structure of porous materials such as rock and concrete, to provide a means for understanding the dependence of...
Restoring the Capitol's West Front
After 25 years of debate, preservation (rather than extension) of the West Front of the U.S. Capitol building in Washington, D.C. has begun. A network of stainless steel rods is being...
Mangrove Creek Dam: Use of Soft Rock for Rockfill
Mangrove Creek Dam is an 80 m high concrete faced rockfill dam (CFRD) completed in 1981. The embankment was constructed largely out of low strength sandstones and siltstones available...
Underground
The Civil and Mineral Engineering Building at the University of Minnesota in Minneapolis was designed with careful attention to the environment. In the years ahead, this building will...
