Abstract: Based on the model experimental results of steel sheet piles cofferdam subjected to lateral loads in the sand and gravel formation near the Songhuajiang river, the experiment is introduced in this paper, including the construction and test methods for the model. The lateral bearing deformation characteristics of the double-row steel sheet piles connected by steel rod are discussed, and are compared with the experimental results of single-row steel sheet piles subjected to lateral loads. By measuring their horizontal movement of depths and displacement of pile top, the alarm values of displacement of pile top and lateral load influence depth are analyzed. The results can be used as reference for the design of similar projects.
