ENERGY DISSIPATION AND LIQUEFACTION AT PORT ISLAND, KOBE

摘要

The Port island, Kobe downhole records from the Hyogo-ken Nanbu earthquake are analysed to obtain approximate histories of shear stress, shear and dissipated energy at a range of depths. Our calculation method relies on measured accelerations in the horizontal plane to produce horizontal Components of shear stress and strain suing instantaneous modal superposition. A simple dissipated Energy-dynamic pore pressure relationship is used to model the development of pore pressure leading to Liquefaction.
