Abstract: This paper presents theoretical as well as experimental results on the bearing performances of the pile-soil system. To sufficiently consider the time effect of geomaterials and the spatial effect of the pile-soil system on pile s bearing performance, a rheological theory of soil for the pile foundation is proposed. Based on the rheological theory, an improved analytical model of pile-soil system is established to analyze the mechanism of spatiotemporal effect on the pile's bearing capacity. Some analytical and semi-analytical solutions of the time and spatial effects of single pile's bearing performance are obtained. This new theory can be used to predict various behaviors of pile foundations, such as the controlling of foundation settlement. In addition, the theory can also be used to validate the construction quality of foundation and to compute the load-displacement relationship of pile, which can supplement the current foundation test technique.
