Some Aspects of Analysis and Prediction of Subsidence
A procedure based on the nonlinear finite element analysis was investigated for the prediction of subsidence caused by longwall mining. This paper presents a case study involving predictions...

Application of a Three-Dimensional Coupled Finite Element?Boundary Element Method
Three-dimensional conditions in underground construction occur at the face of a tunnel, at intersections of underground openings and around roughly equidimensional openings. As long as...

Nonlinear Fracture Process Zone in Rock
A study of the fracture process zone was conducted to gain an understanding of the physics of crack propagation in rock. The nondestructive testing technique of acoustic emissions was...

Oil Shale Fracture Characterization by a New Model
Fracture toughness of oil shale is a property which is essential for fracture characterization needed for energy resource development and recovery. However, a data base for fracture toughness...

Cost Assessment of Construction Noise Control
The results of a series of studies have provided noise control engineers with a method to estimate off-site construction noise levels and the cost of reducing these to acceptable levels....

Site Selection and Building Design for Minimizing Vibration
Over the last five to ten years, line resolutions required for state-of-the-art semi-conductor wafers have dropped to well below 1 micron. As a result, controlling environmental building...

The Eurocodes and Shrinkage in Composite Beams
The two parts of this paper relate to different aspects of design procedures for composite structures of steel and concrete. First, recent developments in the coordination of the eight...

Building on Muck
The Craney Island Disposal Area at Norfolk, Va. is a 2,500 acre depository for material dredged from ports and channels in the Hampton Roads. The U.S. Army Corps of Engineers extended...
