Fraley DEEP FOUNDATIONS The Magazine of the Deep Foundations Institute (DFI) is published bimonthly by DFI. 326 Lafayette Avenue Hawthorne, NJ 07506 USA T: (973) 423-4030 | F: (973) 423-4031 Email: [email protected] High mobility grout (HMG) was injected beneath the historic statues, marble fountain and granite steps that were in “imminent danger” of collapsing due to open voids in the subsurface that were causing ongoing settlement of the fountain. HMG was used to fill the voids in the rubble fill and to prevent future raveling of the subbase material. DEEP FOUNDATIONS • SEPT/OCT 2017 • 5 73 Emergency Stabilization to Maintain CN Rail Service Rick Deschamps, Ph.D., P.E. A system of micropiles installed in an A- Frame configuration along with multiple 12 strand anchors were designed and installed to stabilize the Fountain Slide located about 10 mi (16 km) northeast of Lillooet, British Columbia, Canada, within the Coastal Mountain Range. The author describes the project constraints, design methodology and construction approach used to arrest the movements of this unstable soil mass. 81 Predicting Geotechnical Drilled Shaft Capacity: Are We Close? Vishal B. Patel, M.S.C.E., P.E., Sebastian Lobo-Guerrero, Ph.D., P.E., and James G. Ulinski, P.E. The authors discuss past and current methodology for the design of drilled shafts used in transportation projects. In addition, a case study is presented that uses the results of full- scale load testing to compare predicted and measured resistances of side friction and end bearing.
