摘要：
An excavation for the construction of a cut and cover tunnel has been carried out in deep soft marine clays. Due to practical and economical considerations, the retaining walls comprised braced sheetpiling to support the excavation have been founded in marine clays without being toed into a stronger soil layer at depth. Jet grouting has been used to stabilise the ground below the base of the excavation and to provide lateral support to the sheetpiling during excavation. The performance of the jet grout layer was verified by field tests and monitoring data.
