Abstract
Model test of coastal excavations is based on the excavation of Gongbei tunnel located in the Ling-ding Ocean, which is a part of the famous Hongkong-Zhuhai-Macau Bridge project. A series of model tests are carried out in the ZJU multifunctional wave-current flume to study on the effects of wave factors on the pore pressure response around clayey silt excavation. It is shown that the attenuation of the amplitude of the oscillatory and accumulated excess pore pressure are related to the wave height, the wave period and the water depth. Oscillatory excess pore and accumulated excess pore pressure along with maximum seepage path are affected by various wave factors.
