A numerical model is proposed for the pore pressure build up in soil around a pipeline subjected to horizontal cyclic loading. The model is based on results of centrifuge tests, and the effect of various factors on the pore pressure build up is investigated through some examples using the proposed numerical model. It is found that the pore pressure build up component due to horizontal cyclic loading depends significantly on the initial settlement ratio as well as the ratio of horizontal to vertical load. It is also shown that a peak appears in the pore pressure build up response when the initial settlement ratio is larger than about 0.2.
