Study on Influencing Factors of Deformation of Snowflake Shaped Steel Sheet Pile
Snowflake-shaped steel sheet piles are a new type of special-shaped pile. To study their deformation characteristics under load, numerical simulations and laboratory model test were carried out. The finite difference software FLAC3D was used to construct the numerical analysis model of the snowflake-shaped steel sheet pile, and the validity of the numerical analysis is verified by the results of the laboratory model test. At the same time, the influences of flange number, web (flange) thickness, web (flange) length, pile length, and steel plate elastic modulus on pile deformation are studied. The results show that under vertical loads, the strain of the snowflake-shaped steel sheet pile decreases with increasing depth. Increasing the number of flanges of the snowflake-shaped steel sheet pile can reduce the maximum stress and improve the uniformity of the pile force. Under the same conditions, the strain of the snowflake-shaped steel sheet pile decreases with increasing thickness and length of web (flange), as well as the increasing elastic modulus of the steel plate. With the increase of pile length, the strain of the pile shaft at the same position from the pile top increases, but the maximum strain remains the same, which occurs at the pile top.
