Carbon Footprint Analysis Of A Large Diameter Water Transmission Pipeline Installation
(Civil & Environmental Engineering, 2011-07-14)
The term pipeline refers to a long line of connected segments of pipe, with pumps, valves, control devices, and other equipment or facilities needed for operating the system. Water transmission pipelines are generally large ...
An Overview Of Mitigation Strategies For Settlements Under Bridge Approach Slabs
(Civil & Environmental Engineering, 2012-04-11)
Settlement and heave related movements of bridge approach slabs relative to bridge decks create a bump in the roadway causing inconvenience to the travelling public and at times so large as to make travelling unsafe. Hence, ...
Sustainable Reutilization Of Excavated Trench Material
(Civil & Environmental Engineering, 2012-04-11)
Sustainability is becoming a key factor in most construction projects. In most construction projects, personnel are spending efforts to understand the social, economic and environmental impacts of the various facets of ...
The Effects Of A Variable Modulus Of Elasticity On Prestress Losses In Bridge Girders
(Civil & Environmental Engineering, 2011-10-11)
The purpose of this research is to evaluate a method proposed by Franz Dischinger (Dischinger, 1939) to consider the effects of a variable modulus of elasticity (MOE) of concrete over a period of time. Current guidelines ...
Characteristics Of Fresh Municipal Solid Waste
(Civil & Environmental Engineering, 2010-07-19)
The characteristics of fresh municipal solid waste (MSW) are critical in planning, designing, operating or upgrading solid waste management systems. Physical composition, moisture content, compacted unit weight, permeability ...
Unsaturated Soil Behavior Under Large Deformations Using A Fully Servo/suction-controlled Ring Shear Apparatus
(Civil & Environmental Engineering, 2011-07-14)
In recent years, the key hypotheses of most elasto-plastic constitutive frameworks postulated for unsaturated soils have been validated via suction-controlled oedometer, triaxial, and direct shear testing. These techniques, ...
Effect Of Leachate Recirculation On Methane Generation Of A Bioreactor Landfill
(Civil & Environmental Engineering, 2010-11-01)
Municipal solid waste (MSW) disposal is of current concern due to the green-house effect and rising temperature all around the globe. Landfill gas is generated from aerobic & anaerobic biodegradation of organic materials ...
A Refined True Triaxial Apparatus For Testing Unsaturated Soils Under Suction-controlled Stress Paths
(Civil & Environmental Engineering, 2009-09-16)
A novel, computer-driven, true triaxial (cubical) apparatus has been developed to test unsaturated soil specimens under suction-controlled multi-axial stress paths that are not achievable in a conventional cylindrical ...
Novel Stabilization Methods For Sulfate And Non-sulfate Soils
(Civil & Environmental Engineering, 2009-09-16)
Expansive soils are commonly found in arid and semi-arid climate zone. These soils typically exhibit moderate to high plasticity, low to moderate strength, and high swell and shrinkage characteristic which in turn result ...
Effects Of Calcium-based Treatment On Organic Soil Behavior
(Civil & Environmental Engineering, 2008-09-17)
Organic soils are found in many places around the world. Organic soils undergo large secondary settlements depending on the amount of organic matter present in the soil Organic soil is a mixture of finely divided particles ...
