The invention relates to a test system for a transmission iron tower subjected to horizontal load and foundation tensile action. A fixed steel beam is fixedly connected with the ground through bolts,and the fixed steel beam and a movable steel beam are connected through a loading steel beam, a pressure sensor and a jack; the loading steel beam and steel backing plates fixedly connected at the bottom of the movable steel beam are connected with the ground through a plurality of rollers; four supporting seats at the lower end of a structural model are fixedly connected with the movable steel beam and the fixed steel beam in pairs correspondingly; the upper part of the structural model is connected with a loading platform through a steel wire rope, and a plurality of loading weights are placed on the loading platform; and a concrete wall is fixedly connected to the base ends of two actuators which are arranged at intervals up and down, and the telescopic ends of the two actuators are correspondingly and fixedly connected to the top and the middle of the left side of the structural model. The test system can facilitate the test of horizontal load and foundation tensile action of the transmission iron tower, and can provide theoretical basis for the research of structural safety performance of the transmission iron tower under the horizontal load and the foundation tensile action.The test system is simple in structure, convenient to install and high in reliability.
