In recent years, there have been many research studies focusing on linear data modeling as well as on temporal GIS-T (GIS for transportation) implementations. However, what was fundamentally missing from the research circle was the study of a methodo

A major potential failure mode of thermoplastic well casing is collapse. The casing may be subjected to a collapsing pressure during grouting operations, backfilling, well development or simply from lateral soil pressure. Since the strength of thermo

An experimental test program was conducted to measure the longitudinal permeability of a grouted thermoplastic water well casing system. A neat cement grout, with and without calcium chloride or bentonite admixtures, was placed in the annulus of a si

A software system is developed to analyze and rate existing bridges. The system is capable of rating simple truss and continuous girder bridges up to three spans. Composite and noncomposite steel girders and concrete T-beam bridges are supported. Gir

Cement grout surrounding a well casing generates heat, called heat of hydration, as it hardens. This heat can raise the temperature of the casing-grout-soil system significantly. Because the strengths of plastic casing materials decrease relatively r

Because of the relatively low stiffness properties of thermoplastic materials, casings made from these materials may be more susceptible to collapse. For many applications, when a surrounding material tends to support the casing, the casing resistanc

A method to determine the elastic buckling strength of imperfect closed polygon columns has been developed. A set of eight equilibrium equations was developed but was reduced to a set of four equations by eliminating the displacements at a typical mi

An experimental test program was conducted to determine the parameters influencing the short-term and long-term axial strength of polyvinyl chloride (PVC) and acrylonitrile-butadiene-styrene (ABS) well casing joints. Joint configurations tested inclu

Grouting of water wells is commonly done to increase the well life and to protect the water supply. When Portland cement-based grouts cure, a by-product of the process is heat of hydration which causes increased temperatures in the vicinity of the we
