Indoor pile foundation model test device and method for multiple horizontal cyclic loading working conditions
The invention discloses an indoor pile foundation model test device for multiple horizontal cyclic loading conditions. The indoor pile foundation model test device comprises a pull-out model box with a guide rail, a vacuum consolidation system, a loading system, a PLC control system and a data acquisition system. The loading system is connected with the model pile in the model box through a pile sleeve which can be inserted and locked; the insertion rod is arranged at the port of the force sensor, and the force sensor is designed to be detachable; a vacuum consolidation system for vacuumizing from the bottom is arranged in the model box so as to simulate a real soil body environment; the model box is drawable and is provided with a guide rail, so that the position of a loading system can be quickly adjusted, and multiple groups of tests can be carried out by one-time sample preparation; a PLC (programmable logic controller) control system and an electronic data acquisition system are adopted, test parameters are accurate and controllable, test operation is simple and convenient, and indoor pile foundation model tests under various loading amplitudes and various loading paths such as 0-5kN unidirectional step-by-step loading, unidirectional horizontal cyclic loading, bidirectional symmetric horizontal cyclic loading and bidirectional asymmetric horizontal cyclic loading can be carried out.
本发明公开了一种用于多种水平循环加载工况的室内桩基模型试验装置，包括带有导轨的抽拉式模型箱，真空固结系统，加载系统，PLC控制系统和数据采集系统。加载系统与模型箱内的模型桩通过一可插入锁定的桩套进行连接；插入杆布置在力传感器端口处，力传感器为可拆卸设计；模型箱内设置有从底部抽真空的真空固结系统，以模拟真实土体环境；本发明模型箱的可抽拉及导轨设计，可快速调整加载系统位置，一次制样即可进行多组试验；采用PLC控制系统与电子数据采集系统，试验参数精准可控，试验操作简单方便，可进行0~5kN的单向逐级加载，单向水平循环加载，双向对称水平循环加载，双向非对称水平循环加载等多种加载幅值和多种加载路径下的桩基室内模型试验。
