Qian Y., Zhang G., Yin X., Jin Y., 2018, Experimental Study on the Influence of Moisture Content of Fine Silty Sand on Compressive Failure of Concrete Expanded-plate Pile, Chemical Engineering Transactions, 66, 1129-1134.
This paper mainly studies the influence of moisture content of fine silty sand on the compressive failure state of soil around the bearing plate and the compression bearing capacity of the expanded-plate piles. In the research, the indoor half-section pile small model test and ANSYS finite element simulation are mainly used, and the two types of analysis results are compared to ensure the reliability of the failure mechanism and the bearing theory. The innovative point of this paper is mainly the test method, which uses the form of half-section pile to better observe the entire experiment process from the loading of the concrete expanded-plate (CEP) piles to the failure of the soil; the test soil adopts fine silty sand and uses a self-made soil loader which can be disassembled, taking into account the influence of moisture content, an important influencing factor on the bearing capacity. The test method is more feasible and the test results are more reliable.
