Numerical Modeling of Air Losses in Compressed Air Tunneling
Publisher: American Society of Civil Engineers
Abstract: A numerical model has been developed to predict the air losses from tunnel face and perimeter walls in compressed air tunneling. The model can also predict the zone of ground influenced by air flow from the face and walls ...
Effect of Freezing on Stress–Strain Characteristics of Granular and Cohesive Soils
Publisher: ASCE
Abstract: To investigate the stress–strain behavior of frozen soils, a program of triaxial compression tests was designed and carried out on samples of unfrozen and frozen cohesive (CL) and granular (SP) soils and pure ice. The ...
Numerical Modeling of Contaminant Transport through Soils: Case Study
Publisher: American Society of Civil Engineers
Abstract: This paper presents the development and validation of a numerical model for simulation of the flow of water and air and contaminant transport through unsaturated soils. The governing differential equations include two mass ...
Effect of Cement on Treatment of a Clay Soil Contaminated with Glycerol
Publisher: American Society of Civil Engineers
Abstract: An investigation into the behavior of a contaminated clay soil and its treatment was carried out through a program of experimental tests. The contaminated soil samples were prepared with different percentages (3, 6, and ...
Effect of Resin on the Strength of Soil-Cement Mixture
Publisher: American Society of Civil Engineers
Abstract: A mixture of soil-cement and acrylic resin is used to improve the engineering properties of the soil for construction. This paper presents the results of an investigation into the mechanical behavior of soil-cement mixtures ...
Mechanical and Leaching Behavior of a Stabilized and Solidified Anthracene-Contaminated Soil
Publisher: American Society of Civil Engineers
Abstract: This paper presents an investigation into the remediation of an anthracene-contaminated clay soil through experimental tests. Samples were prepared of uncontaminated and contaminated soil-cement with 20 and 30% cement. ...
Effect of Hysteresis on the Critical State Behavior of an Unsaturated Silty Soil
Publisher: ASCE
Abstract: In this paper the effect of hysteresis on the critical state behavior of unsaturated soils is investigated through conducting a number of controlled suction triaxial tests on samples of an unsaturated silty soil. The slurry ...
Effect of Cement on Treatment of a Clay Soil Contaminated with Glycerol
Publisher: American Society of Civil Engineers
Abstract: An investigation into the behavior of a contaminated clay soil and its treatment was carried out through a program of experimental tests. The contaminated soil samples were prepared with different percentages (3, 6, and ...
