“…A simplified numerical framework, known as the -formulation, was formulated by assuming Darcy's flow rule (laminar flow) and neglecting the fluid inertia [7,[16][17][18]. By denoting was the flow rate of the fluid, we thus have the overall balance or momentum equilibrium equation of soil-liquid mixture as [19]…”

“…Vectors f and f represent the effect of body forces along with prescribed boundary conditions for the solid-fluid mixture and fluid phases. The model used to simulate the dynamics behavior of the soil is the Pastor-Zienkiewicz mark III (P-Z III) model, which has been recognized as the model most suitable for modeling materials susceptible to liquefaction [19]. The model was proposed in 1985 by Pastor et al for saturated sands subjected to dynamic excitation and liquefaction was imminent.…”

“…Detailed description of the theory and constitutive relation for P-Z III can be found in, for example, Merodo et al [20]; Khoei et al [10]; Borowiec [19], Zienkiewicz and Mroz [8]; they are thus not repeated here.…”

The island of Taiwan is located between the boundaries of the Eurasia and the Philippines Plates and thus earthquakes occurred frequently. The excitation of earthquake affects the integrity of earth dams situated in the mountainous area of the island. A study was conducted to evaluate the dynamic response and safety of one of the earthquake dams. The computer program and soil model used were calibrated for their appropriate use for the subject dam against a well-instrumented centrifuge model. Numerical simulation was then conducted to examine the influence of upstream water storage level on the response of the earth dam. The numerical results identified three locations in the dam where attentions are required because these locations were found susceptible to liquefaction.
