QA/QC for Jet Grouting in Deep Boston Blue Clay: Central Artery/Tunnel Project
An extensive pre-construction test program was performed to develop installation parameters that would result in overlapping jet grout columns with diameters of at least 1.5m. The columns were to be installed through approximately 40m of fill, organics and clay deposits; and 0.3m into the underlying glacial deposit. This paper describes the technical difficulties encountered during the test program; the different methods adopted to assess the effectiveness of the jet grouting; and the QA/QC criteria eventually adopted for installing and accepting the in situ grout columns.
