摘　　要：针对松花江砂卵石地层上的钢板桩围堰进行现场模型的水平载荷试验,介绍了模型的施工及试验方法,研究了双排钢板桩通过拉杆连接这种结构在水平载荷作用下的变形特性,同时进行了单排钢板桩水平载荷试验作为对比分析;通过测量其深层水平位移及桩顶位移,分析其桩顶位移预警值为及水平荷载的影响深度;通过测量拉杆轴力,分析水平力的传递,对类似工程设计有一定的参考作用。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.
