Behavior of Instrumented Model Piers in Manufactured Rock with a Soft Layer

Document Type: Proceeding Paper

Part of: Design and Performance of Deep Foundations: Piles and Piers in Soil and Soft Rock

Abstract:

A laboratory test apparatus has been used to study the side resistance of piers socketed into manufactured soft-rock masses. The results of four tests are reported, three of which included horizontal soft seams of different thicknesses. The rock material was simulated with a plaster-sand mortar, and the soft seam with a plaster-styrofoam bead mortar. The mobilized side resistance is compared with predictions from existing empirical methods, and the effect of discrete soft seams or inhomogeneities on the side resistance and displacements is evaluated.
