Abstract

An extensive soil improvement program was developed for the Vultri Container Terminal, Italy, located on an Hydraulic Reclamation Fill. The Office and Warehouse Building, and the Light Tower foundations were supported by Jet Grouting Columns. A testing program was developed, including coring and nondestructive testing on the columns, to verify the as built conditions. Test results show the difficulties in evaluating Jet Grouting properties with a nondestructive approach, mainly related to the complex geometry of the columns. However, the analysis and the comparison of the wave records provided suggestions on the most effective testing procedures, and on the possibility of estimating the variation in column diameter.

A Non Destructive Testing Program for a Group of Jet Grouting Columns

St. Louis, Missouri

An extensive soil improvement program was developed for the Vultri Container Terminal, Italy, located on an Hydraulic Reclamation Fill. The Office and Warehouse Building, and the Light Tower foundations were supported by Jet Grouting Columns. A testing program was developed, including coring and nondestructive testing on the columns, to verify the as built conditions. Test results show the difficulties in evaluating Jet Grouting properties with a nondestructive approach, mainly related to the complex geometry of the columns. However, the analysis and the comparison of the wave records provided suggestions on the most effective testing procedures, and on the possibility of estimating the variation in column diameter.
