Creep Fracture in Rock in Uniaxial Compression

Abstract

Three rock types, a granite, a sandstone and a marble, were tested in uniaxial compression to assess the time dependent properties of brittle rocks at stress levels exceeding half the uniaxial compressive strength. Specimens were tested in quasi-static tests and in creep and differential creep experiments at room temperature. The effect of (partial) pore water pressure was considered by comparing air-dried and water-saturated samples. Particular mathematical descriptions of time dependent deformations were derived from creep and differential creep tests.
