Abstract
This work uses ANSYS software to simulate and analyze the new flexible concrete expanded plate (NT-CEP) piles, mainly evaluating the anti-overturning bearing performance of NT-CEP piles with different plate cross-sectional forms and the damage state of the soil around the pile. The software is used to design four groups of model piles with different plate cross-sectional forms and conduct an in-depth analysis of the displacement cloud diagram, load—displacement curve, and stress cloud diagram after load failure. The pile-soil force mechanism and failure law are obtained, and the flexible NT-CEP is analyzed. The calculation model of the ultimate horizontal bearing capacity of the NT-CEP piles supplements the theoretical results of the concrete expanded piles under horizontal loads and provides theoretical support for its design and popularization in practical engineering.
