Analysis of the Installation Effect on the Axial Performance of Pressure-Grouted Helical Piles in Clay by Small-Scale Model Tests
نویسندگان
چکیده
A pressure-grouted helical pile (PGHP) is a stiffened installed by using the simultaneous drilling and grouting technique. The formation of soil-cement column surrounded influenced multiple installation parameters, including helix number, size, speed. series small-scale model tests was carried out in clay to investigate influence parameters on axial behavior PGHP load transfer mechanism. piles were pulled after loading tests, dimensions columns measured. ultimate compressive bearing capacities PGHPs 260% 293% higher than un-grouted piles. proportional increase number size decreased with average bond diameter 1.26 1.35 times size. adhesion between surrounding range 0.8 1.2. overall results examine feasibility technique improvement performance compared
