PHYSICAL MODELING OF PIERS SOCKETED INTO SOFT ROCKS

This paper addresses some fundamental factors that affect the shaft frictional resistance of piers socketed in soft rocks subject to static loading. Constant normal load direct shear tests were conducted on various rock-concrete interfaces consisting of sawtooth asperities with different inclinations. Model piers with smooth and rough surfaces were constructed and pushed into rock sockets using an MTS load frame. The response of those piers was compared to the empirical predictions of Williams and Pells, Rosenberg and Journeaux, and Horvath et al. (A) This paper was presented at the 34th U.S. Symposium on rock mechanics, 27-30 June 1993, University of Wisconsin-Madison. For the covering abstract see IRRD 863389.
