Jet Grouting: New Directions

Abstract:

This article looks at jet grouting in soft soils, especially applications involving pre-installed structural supports for cut and cover excavations. The author offers a question and answer approach to deciding when jet grouting might be an appropriate solution for a site. The most important factors are whether the ground water can be drawn down around the excavation, whether ground movement can be tolerated, and whether movements can be economically controlled with lateral bracing. If the answer is yes to all questions, conventional methods such as sheeting, bracing, anchors and dewatering would be appropriate and cost-efficient. If the answers to some of the questions are no, the author suggests alternative actions to determine whether jet grouting would be an economic solution. Jet grouting is appropriate when conventional methods are unsafe or too costly. Several case studies in California where jet grouting was used for pre-installed bottom supports are described.
