Abstract本发明提供一种模拟循环载荷下板锚极限动承载力的测试系统,包括:板锚模型、用于将板锚模型的锚胫限定为垂直于床面移动的十字支撑架、循环载荷加载装置和测量装置;循环载荷加载装置用于向锚胫施加循环载荷,包括将电机输入的匀速转动转换为模拟正弦的往复转动的传动装置、将往复转动转化为指定常荷载与模拟正弦荷载叠加的循环荷载位移载荷转化装置和用于根据板锚模型的位移调整绳索的长度,使循环载荷的幅值不因多周期的累积板锚模型位移而发生衰减的位移修正装置。本方案能有效控制循环载荷的幅值、获得循环拉拔过程中板锚周围土体的孔隙水压,直接观测板锚及其周围土体的破坏过程,对循环载荷下板锚的极限承载性能进行合理评估。
