A New Model for Pore Pressure Generation for Evaluating Wave-induced Liquefaction

摘要

Seabed stability is affected by factors pertaining to cyclic wave loading, such as wave-induced single external stress or internal stress, the number of cycles in the seabed, and the pore pressure generation model (i.e., the earthquake mechanism). On the basis of cyclic triaxial tests, this study proposes a pore pressure generation model for seabed subjected to long-term wave loading by using a hyperbolic sine function and suggests a testing parameter to predict the curve of pore pressure under different test conditions with various T-p. Moreover, the proposed model is integrated with a simple evaluation methodology for liquefaction analysis considering wave loading.
