摘要：

Experimental laboratory-scale studies were conducted on the effect of the use of various mineral and polymer drilling slurries on the perimeter lend transfer in drilled shafts in saturated sand. Parallel measurements were also made of the theological properties of the slurries studied in order to develop ranges of slurry control properties consistent with predictable load transfer. Polymer slurries, mixed in medium to high doses, were found to be as effective as the more familiar mineral slurries in the development of load transfer. No slurry, however, produced the magnitude of perimeter lend transfer that was developed on model drilled shafts constructed by inserting casing ahead of the drill in medium-dense, saturated sand and withdrawing the casing as the simulated concrete was placed.
