In-situ answering pore pressure under wave and its application to stability analysis of silty seabed

Silt is easy to liquefy under cyclic loading such as wave effect.and excess pore pressure plays an important role in dynamic behavior of silt soil and its change can affect seabed stability directly.The relation between excess pore pressure and wave in silty seabed is studied in this thesis by means of model experiment of answering pore pressure under wave.Besides,the thesis summed up two methods to estimate porepressure under wave and put forward a method to envalue the stability of silty seabed according to the result of the model experiment.
