【 摘 要 】

Through dynamic triaxial tests of the saturated remolded loess, the pore water pressure generation characteristics of the samples are analysed during liquefaction processes. Based on dynamic triaxial test results, pore pressure generation characteristics of remolded sample are discussed, the effect of confining pressure on the generation of excess pore water pressure is evaluated, the particularity of pore pressure generation by comparing with the predecessor's research results is pointed out and the normalized pore pressure growth model is given. Finally, fitting curve of pore water pressure growth is drawnby using this model and fitting parameters are given.
