Scientific Visualization of Soil Liquefaction
Little is known about the soil liquefaction behavior and visualization at depth. This study focuses on the liquefaction behavior at different depths, and uses the scientific visualization to enhance our understanding of the liquefaction phenomenon. A scientific visualization scheme incorporating combination of three-dimensional volume visualization and ray casting techniques with animation is developed for the purpose of studying the liquefaction behavior. A fast parallel volume rendering algorithm using raycasting, sparse octree techniques, and interactive transfer functions has been developed to establish coupled techniques for evaluation of soil liquefaction data. Data from the experimental centrifuge tests including cyclic shear stress (to result in liquefaction), cyclic shear strain, acceleration, and excess pore pressure as a function of time for four different depths ranging from 2.12 m to 12.65 for a two-layer soil specimen was used. The results have indicated that the scientific visualization is a valuable tool that can properly characterize the liquefaction behavior and provide an insight into a phenomenon that was not previously possible.
