Ecological Research on Moisture Content of Clay Soil Affecting Failure Behavior of the CEP Pile under Vertical Load

In environmental engineering the concrete expanded-plate pile (The CEP pile) is a new type pile, which is different from the ordinary cast-in-place concrete pile, through the special device, the bearing plate is set in the specific position of the pile, so the bearing capacity of the pile can be improved ecologically. Clay soil is the main soil layer used for burring the bearing plate, because the moisture content of clay soil layer has a certain influence on bearing capacity, in this paper, the changes of uplift bearing capacity of the CEP pile and soil failure behavior in the case of different moisture content are studied by environmental engineering model test of undisturbed soil, and it will be simulated and analyzed by using ANSYS finite element software, the analysis results are compared and come to a conclusion, and then the existing design theory of the CEP pile can be perfected, which can provide reliable theory basis for the popularization and application of this type of pile and develop solutions to environmental problems.
