From Theory to Practice: SANISAND Model for Cyclic Liquefaction – Numerical Implementation, Automatic Calibration, and Application

This research project is dedicated to advancing seismic analysis practices for geological structures. The primary objective is to develop a suite of reliable and user-friendly modeling tools to enhance our ability to predict and mitigate the effects of earthquakes, particularly focusing on soil liquefaction. This involves robust numerical
implementation of an advanced sand constitutive model into several state-of-the-art and practice numerical modeling software programs, an intuitive automatic calibration tool for model parameters, and a repository of practical applications for achieving a reliable simulation of the seismic displacements resulting from liquefaction. The project is divided into four tasks, each contributing to the overall goal of improving seismic resilience and the safety of critical infrastructure. The research is not only significant for advancing the state of practice in the analysis of seismic-induced liquefaction of granular soils but also in bolstering the competitiveness of Canadian engineering on a global scale and training future experts in the field. Ultimately, the aim is to empower engineers and researchers to make informed decisions, leading to safer communities and more resilient infrastructure.
