Jet Grout Stabilization of Peaty Soils Under a Railway Embankment in Italy
The construction of two railway embankments on a peaty soil deposit up to 7m thick required a foundation improvement program meeting very strict specifications in terms of environmental...

Jet Grouting for Underpinning and Excavation Support
Jet Grouting as a new tool for underpinning and excavation support is presented, describing the systems of Jet Grouting and its advantages over conventional underpinning techniques. A...

Jet Grouting to Construct a Soilcrete Wall Using a Twin Stem System
An existing coal loading pier located in Norfolk, Virginia was completed in 1961 for the purpose of loading ocean going ships. It was determined that dredging adjacent to the pier would...

Analysis of Barrier Island Dynamics for Ship Channel Planning at Ship Island, Mississippi
Ship Island is located among a chain of barrier islands approximately 18 km south of Biloxi, Mississippi. During initial construction of Gulfport Harbor Ship Channel, 1901-1905, the channel...

In Situ Determinations of Dispersion and Transport Parameters at Piraquara De Fora (RJ)?Brazil, With Help of a Fluorescent Dye Tracer
This paper deals with 'in situ' determinations of the transport and dispersion parameters at Piraquara de Fora cove, near the site where the first Brazilian nuclear...

Convection in the Classroom
By their nature, the empirical relations used to calculate convective heat transfer coefficients offer the user little or no insight into how the typical input parameters, e.g., pipe diameter...

Interactive Aircraft Section Calculations for Drag
Large interactive computer programs are being called upon with increasing frequency for the preliminary and conceptual design of aircraft. One drag component which can be estimated at...
