Abstract: Dynamic cyclic loading tests of the soils with va rious fine content are carried out with different strain level from low to high. Based on t he viewpoint of total energy dissipation, the effects of the following factors o n the excess pore water p ressure are studied:fine content,confining pressure, loading frequency, loading s tep and irregularity of loading. A normalization method is put forward for the e xc ess pore water pressure and total energy dissipation. An excess pore water p ressure rising model is established for the sandy clay. Relationships between mo del parameters and fine content of soil are discussed finally.
