Grouting to Minimize Settlements Prior to Tunnel Excavation – A Case Study
D. Heenan, M. Xu
Phase 1 of the Glen Echo Creek Culvert Reconstruction Project involved lowering the invert of an existing concrete arch tunnel along with replacing an existing corrugated metal pipe (CMP) with a new tunnel between 28th and 29th streets in Oakland, California. All construction work was performed within the tunnel by hand mining techniques. Due to the close proximity to residential buildings, roadways and utilities, various grouting techniques were applied to minimize ground settlement, stabilize subgrade soils and reduce water seepage to facilitate hand excavation. This paper describes the design and execution of the various grouting programs implemented, as well as the grouting performance.
