RESEARCH ON INFLUENCE OF ADJACENT CLAY-LAYER THICKNESS FOR THE FAILURE BEHAVIOR AND PERFORMANCE OF THE MEEP PILE UNDER VERTICAL COMPRESSION

摘要

This paper uses the ANSYS software to establish the finite element analysis model, the MEEP pile is set in the soil layer with different characteristics, under the effect of vertical compression, by changing the thickness of adjacent clay layer under the bearing plate, it is analyzed that the failure behavior of the soil surrounding the pile, and the compression resistance performance changes of the MEEP pile, the influence of adjacent clay-layer thickness under the bearing plate for the MEEP pile is determined, which will further improve the calculation mode of compression bearing capacity of the MEEP pile, provide a reliable theoretical basis for the design of this type of pile.
