| Abstract: | Researches on rock dynamics related to a cavern development project for ammunition storage in Singapore have been carried out. The researches include the study of dynamic properties of rock material (strength, modulus, constitutive relations), dynamic normal and shear properties of rock joints, shock wave propagation across joints and through the rock mass, and dynamic response of the rock mass and structures in rock using the discrete element method. The results obtained from the research works provide the necessary input to the design and construction of the cavern project. |
