英文摘要	The mechanical behaviors of cemented granular soils under undrained conditions and cyclic loads were determined through numerical simulations and the details about the contact network and bonds of numerical sample were investigated. The evolution of the internal structure of the samples subjected to cyclic loads was analyzed based on the results of parameters from a complex network. The results showed that the evolution of the residual pore-water pressure strongly correlated with the parameters of complex network and a new pore-water pressure model was proposed based on these parameters. Therefore, the evolution of the mesostructure can be used to describe the development of the pore-water pressure generated in granular cemented soils.
