摘要：
This study used the Massachusetts Institute of Technology general circulation model (MITgcm) to simulate the seabed liquefaction process in the Chengdao area. The liquefied soil and the overlying water are considered as a two-layer fluid system in the model. By constructing various topographies using Gaussian functions, it is possible to achieve an agreement between simulation and measurement. The simulation results reveal the characteristics of pore pressure in different topographies. The main findings include the following: (1) The expansion of liquefaction zone leads to an accelerated attenuation of pore pressure amplitude. (2) A decrease in topographic slope diminishes the wave group characteristics of pore pressure due to the sensitivity of certain wave components with specific frequencies to topographic slope.
