摘要： A p-y curve-based element test device is provided. An upper support plate is located above a lower support plate and is fixedly connected to the lower support plate through truss supports symmetrically arranged on left and right sides, and at least one truss support is arranged on each side. A sample container, a servo consolidation mechanism and multidirectional servo actuators are connected to the truss support on the two sides. The servo consolidation mechanism is located above the sample container, and the multidirectional servo actuators are arranged above the servo consolidation mechanism and below the sample container, respectively. Identical loads are synchronously applied from above and below to realize horizontal movement of a pile element to simulate the load condition of a soil body, and a pressure is applied by a servo consolidation device to simulate the stress condition of the soil body at a certain depth.
