Numerical Modeling Of Ground Movements Associated With Trenchless Box Jacking Technique
(Civil & Environmental Engineering, 2014-09-17)
The Trenchless Technology (TT) is defined as a family of methods used to install, renew, replace or renovate new pipe/box or existing pipe/box underground with little or no surface disruption. TT is divided into two main ...
Non-destructive SASW Evaluation Of Controlled Low Strength Material As A Pipeline Bedding Material
(Civil & Environmental Engineering, 2014-09-17)
Evaluation of stiffness properties of subsurface soil layers provides vital insight into the performance of a geotechnical entity. Stiffness properties can be determined by both field and laboratory tests. Owing to their ...
Stabilization Of High Sulfate Soils
(Civil & Environmental Engineering, 2013-10-22)
Stabilization of expansive soils using lime and cement has been a favorite technique for practitioners over the years. However, recent heaving and premature pavement failures in lime and cement treated subgrades containing ...
Assessment And Rating Of Mechanically Stabilized Earth Walls
(Civil & Environmental Engineering, 2013-03-20)
Mechanically stabilized earth (MSE) walls have been increasingly utilized in the United States since 1972 and in Texas since 1979. MSE walls provide earth retention for commercial, industrial and transportation projects ...
Performance Of Large Diameter Polyvinyl Chloride (PVC) Pipes In Water Applications
(Civil & Environmental Engineering, 2014-03-10)
Polyvinyl chloride (PVC) pipes with diameters greater than 24" make up a small fraction of water utilities. Most of the research done on PVC pipes in water utilities focuses on diameters less than 24". Therefore, this ...
LRFD Pullout Resistance Factor Calibration For Soil Nails Incorporating Survival Analysis And PLAXIS 2D
(Civil & Environmental Engineering, 2013-10-23)
The use of soil nail walls (SNWs) in the United States has increased since their introduction in the mid-1970's, to where currently the analysis, design and construction are commonly performed (Lazarte, 2011). These SNW ...
Identifying Issues Impacting Productivity Of Box Jacking Projects
(Civil & Environmental Engineering, 2013-03-20)
Jacking is a trenchless construction technique used for installing underground pipeline system. Jacking method is more widely used for upgrading under capacity culverts and drainage structures under roads and railroad ...
An Evaluation Of Failure Modes For Cast Iron And Ductile Iron Water Pipes
(Civil & Environmental Engineering, 2013-03-20)
The need to evaluate the performance of cast iron and ductile iron water pipes is of great importance since they are the most common pipe materials for water mains. The concern in the water industry is about the cost ...
Comparison Of Measured And Predicted Response Of Six MnRoad Asphalt Test Sections
(Civil & Environmental Engineering, 2013-03-20)
The study, sponsored by MnRoad, aimed to compare the measured and predicted values of strains and stresses for six cells 33, 34, 35, 77, 78 and 79 of the third MnRoad experiments. Cells 33, 34 and 35 were constructed for ...
An Evaluation Of Large Diameter Steel Water Pipelines
(Civil & Environmental Engineering, 2013-03-20)
Steel water pipelines, as a part of America's underground infrastructure, play a key role in maintaining the quality of life and well-being of communities. Thousands of miles of steel water pipelines make up a huge and ...
