FEM Analysis of Staged Construction for a Reinforced Earth Wall
Transport of Volatile Organic Compounds (VOCs) Through a Clay Liner
A series of tests have been performed using laboratory-scale flexible wall permeameters. A synthetic organic leachate mixture of methylene chloride, toluene, and trichloroethylene (TCE)...
Influence of Moisture Influx on the Hygro-thermal Performance of a Clay Buffer Developed for Nuclear Disposal Vault
This paper focusses on an experimental study that investigates the heat transfer and moisture movement within a bentonite clay buffer compacted in a borehole located in a granite block....
Rocky Mountain Project Conceptual Design of Upper Reservoir
The 9300 acre-foot upper reservoir for the Rocky Mountain Project will be formed by an 80-ft high ring dam with a crest length of 12,800 feet. Sandstone and shale of the Pottsville formation...
Lysimeter Studies in Irrigated Soils of South Eastern Australia
The Riverine Plain of south eastern Australia is an extensive, predominantly clay soil area with large surface irrigation schemes. Early lysimeter installations were used to estimate evaporative...
Comparation of Different Forms of Penman Equation
The research was carried out near Foggia (in Southern Italy) at 90 m above sea level and at 41° 27' N latitude, using two drainage lysimeters, filled with a silt clay soil...
Temporal Ion Balance Variation of an Irrigated Soil
The research was carried out in Southern Italy, from 1983 to 1988, using two gravity lysimeters irrigated with non saline water. The objective of this study was to test wether long-term...
Validation of Source-Term Models Using Natural Analogues
A comparison is made between the predicted distribution of copper calculated by the AREST source-term code and the measured profiles for copper surrounding a bronze cannon that was emplaced...
Thermal Strain Behaviour of Clays Cooled to Cryogenic Temperatures
The thermal expansion behaviour of two different types of clays (Boom clay from Belgium and a pure kaolinite-water paste) has been studied in a temperature range from +20° to -150°C (LNG...
Reliability Analysis for Time of Travel in Compacted Soil Liners
Time of travel through compacted soil liners is difficult to predict because numerous factors confound the analysis. In this paper, the influence of spatial variability and uncertainty...
Scale Effects in Cone Penetration Tests
A field testing program was undertaken to examine the existence of scale effects between a miniature 1.27 cm2 and 15 cm2...
A Reinforcing Method for Earth Retaining Walls Using Short Reinforcing Members and a Continuous Rigid Facing
Volume-Controlled Approach for Direct Measurements of Compressibility and Hydraulic Conductivity
Designing Vitrified Clay Pipe Systems with EASE
NCPI has developed a computerized trench load design program which provides a broad and complete spectrum of design options which will enable engineers and contractors to safely design...
What Will be the Engineered Barriers for Deep Disposal of High Level Radioactive Wastes in the Future?
Two sealing approaches are currently being developed in France for deep geological disposal of high-level wastes. One is based on the use of swelling clay in order to restore the initial...
Comparison Between the Field and Laboratory Measured Properties of a Clay Liner
Hydraulic conductivity (K) and bulk density (BD) of an experimental clay linear were evaluated at a large number of locations using standard methods. They were then compared to laboratory...
The Behavior of Bridge Abutments on Clay
External Stability of a Reinforced Earth Wall Constructed Over Soft Clay
Shoring Failure in Soft Clay
Effect of Water Depth and Groundwater Table on Infiltration from Recharge Basins
The actual effect of water depth on infiltration depends on the depth to groundwater and on whether the wetted perimeter of the basin is clean or covered by a clogging layer of fine particles...
