A case study of slope open-cut and self-stand two-row sheet piles used in excavation is presented in this paper. The involving stiffness and deformation behaviors of self-stand two-row sheet piles during excavation are interpreted and summarized in this paper based on the data resulting from fied monitoring and observation. Although the measured deflections of sheet piles in-situ are more larger than estimation and braced system is adopted to finish excavation finally. We still expect to have some help in understanding and further research of this technique.
