Study Institute of Geotechnical Engineering, Hohai University, Nanjing 210098, China Correspondence: [email protected]: As a newly created pile foundation, the snowflake shaped steel sheet pile is composed of 3 Y-shaped sections with an included angle of 120 and features a large precise surface location, which can give full play towards the side friction of pile and increase the bearing capacity of single pile. At the similar time, the snowflake shaped steel sheet pile has a high strength, fairly handful of components, and it has very good prospects with engineering applications. So that you can accurately grasp the mechanical characteristics from the snowflake shaped steel sheet pile, this paper carried out the model test of snowflake shaped steel sheet pile based on OFDR (optical frequency domain reflector) distributed optical fiber sensor technologies. The outcomes show that: (1) OFDR distributed optical fiber sensing technologies can proficiently monitor the strain of snowflake steel sheet pile; (two) below the vertical load, the strain of snowflake steel sheet pile decreases along the length in the pile; (three) the strain from the identical section of snowflake steel sheet pile is distinct at unique positions, the strain in the junction involving net and web is essentially exactly the same as the junction amongst net and flange, and the strain with the pile shaft around the flange edge is larger.Citation: Gao, L.; Xu, Z.; Wang, Q.; Zhang, Z.; Li, P.
