【摘要】采用同济大学土动教研室设计的模型箱设备对不同含水率下的铁矿粉进行一系列的动力试验。试验中通过施加一定频率的动荷载来模拟波浪荷载，通过对铁矿粉的试验观察分析以及对采集的孔压变化进行分析，从而着重探讨了含水率对铁矿粉的动力特性影响，为实际海运铁矿粉提供可靠的含水率范围，具有一定的现实意义。

[abstract] This paper utilize the model box system designed by soil dynamic department of tongji university, making a series of dynamic test of different moisture content of iron ore powder. In the test, by exerting dynamic loads of the settled frequency to simulate wave loads, the phenomenon with the acquisition of the experimental observation and analysis and pore pressure change of iron ore powder are analyzed to discuss the influnce of moisture content of the dynamic properties of iron ore powder, which can provide reliable moisture content range for actual shipping, and has certain practical significance.
