Rock dynamics research related to cavern development for ammunition storage

Researches on rock dynamics related to a cavern development project fbr amm unition storage in Singapore have been carried out. The researches include the study of dynamic properties of rock material (strength, modulus, consti tutive relations), dynamic normal and shear properties of rock joints, shoc k wave propagation across joints and through the rock mass, and dynamic res ponse of the rock mass and structures in rock using the discrete element me thod. The results obtained from the research works provide the necessary in put to the design and construction of the cavern project. (C) 2000 Elsevier Science Ltd. All rights reserved.
