Preferred Design Procedure

<p><p><h2>Preferred Design Procedure</h2>There is no FHWA design guidance for jet grouting. Three existing design methods for jet grouting were assessed, including design using computer analysis, design based on estimates from experience, and jet penetration distance based on a fluid-soil interaction model. These design methods are not proprietary.</p><p>With multiple existing design procedures, guidance for selecting the correct procedure is needed. Due to the proprietary nature of jet grouting, this selection process and the detailed design process should be performed by a specialty contractor experienced in jet grouting. Table 2 gives typical inputs and outputs for design and analysis of jet grouting projects.</p><p>See the <em>Design Guidance</em> document for column-supported embankments for recommended design procedures for the arching/load transfer mechanism from the embankment to the jet grouted columns, and for slope stability analyses.</p></p>
