Mechanical Model of Weak Plane for Finite Element Analysis in Rock Mass Engineering-Weak Plane Element Analysis

Time Averaged Estuarine Mass Transport Equations
A methodology for deriving time averaged mass transport equations for estuaries having weakly nonlinear long wave dynamics is presented. A 2D in-plane advection-dispersion equation for...

Leakage from Pressure Tunnels and Shafts
Several issues related to leakage from unlined pressure tunnels and shafts are reviewed and discussed. They include confinement, or cover requirements relative to hydraulic jacking of...

Thermal Monitoring of Leakage Through Dams
The technique involves very accurate temperature measurement at shallow depth below the reach of the surface diurnal cycle. Temperatures respond to subsurface water movement (with advective...

Stabilization of a Permafrost Subsidence in the Airport Runway at Bethel Alaska
During the construction of the extension to the Bethel Airport runway in 1969, it was necessary to construct a fill across a small gully. The subbase material in the gully contained some...

Finite Element Modelling of Cold Regions Concreting
Finite element heat transfer computer programs are discussed in regard to their use in modelling cold weather concreting. The concrete material properties required for input to the finite...

Subtidal Circulation and Transport in Estuaries

Landslide-Generated Wave Studies
A serious safety of dams problem is associated with large masses of rock and debris plunging into lakes and causing damaging water waves. This concern prompted the Bureau of Reclamation...

Estimation and Inference in the Inverse Problem
The estimation of groundwater flow and mass transport parameters is approached via maximum likelihood. Confidence intervals and hypothesis tests as well as the asymptotic properties of...

A Study of Exterior Facades—Problems and Solutions
The quality of the exterior facades of a building is important to maintaining aesthetic image, protecting the interior environment from infiltration of heat, cold, moisture, wind, and...

A Mesh Generator for the Modeling of Rock Discontinuities
The need to characterize a rock mass by collecting field data is receiving more and more emphasis as larger, more ambitious underground structures are being built. Yet there is a need...

Geotechnical Data Acquisition and Computerized Analysis
In 1983 and 1984, an exploratory tunnel was constructed as part of the geotechnical exploration program for two highway tunnels to be constructed for the improvement of Interstate 70 through...

Computerized Construction Progress Control
In 1983 and 1984, an exploratory tunnel was constructed as part of the geotechnical exploration program for two highway tunnels to be constructed for interstate 70 through Glenwood Canyon,...

Air-Water Oxygen Transfer at Spillways and Hydraulic Jumps
Dissolved oxygen measurements are reported for seven spillway structures in the vicinity of Minneapolis, Minnesota, corresponding to 27 individual surveys. The surveys are taken during...

Performance of Viscoelastic Structural Dampers for the Columbia Center Building
Vibratory motion of structures such as buildings, bridges, and floors can be reduced by the use of viscoelastic (V. E. ) dampers. Such dampers transfer part of the vibratory energy of...

Modeling the Movement of Volatile Organic Chemicals with Unsaturated Flow
Over the past decade, the rate of groundwater contamination by volatile organic chemicals (VOCs) has increased. Therefore, for both groundwater protection and cleanup, it is necessary...

A Combined Limit Equilibrium and Statistical Analysis of Wedges for Design of High Rock Slopes
This paper describes a unique technique developed for the statistical analysis of wedge failures which control the design of high slopes in relatively hard jointed rock masses. Using this...

A New Approach to Activated Sludge Plant Design
Activated sludge plants are designed on the basis of stationary tests at laboratory scale for constant organic loads and constant input flows. From these tests the kinetic parameters are...

Rock Masses
Modeling of Underground Openings/Probability of Slope Failure/Fracture of Intact Rock
While soil mechanics has been the dominant interest of Civil Engineers since Karl Terzaghi's recognition of the principle of effective stress, rock mechanics is becoming increasingly...
