摘要：A 2.5 meter diameter 49 m long concrete shaft foundation socketed into rock was load tested with a system of balanced internal jacks similar to the O-cell test. This internal loading provided an examination of the skin friction response both above and below the load jack. Based on the observed response, the properties for the interface between the concrete and rock-socket were back-calculated. Since the observed side resistance at the interface was greater than the resistance due solely to friction, an apparent interface cohesion term was included by idealizing small asperities along the rock socket. The use of idealized asperities appears to be an effective way to model cohesion at the rock-concrete contact.
