Behaviour of Singapore Rocks under Uniaxial & Triaxial Loading

摘要：

This paper describes the strength and deformation behaviour of Jurong Formation sedimentary rocks in Singapore. In this study, uniaxial and triaxial compressive tests as well as indirect tensile tests had been carried out on different sedimentary rocks, i.e. siltstone, limestone, sandstone and mudstone. During the tests, the axial and lateral deformations of the rocks were monitored against the stress level. In addition, acoustic emission and change in ultrasonic velocities during loading were recorded as well. Various aspects of the rock behaviour such as stress thresholds identification, effects of confining pressure on stress thresholds, acoustic emission tests, ultrasonic tests, Young’s modulus and Poisson’s ratio and failure criteria were elaborated in this paper.
