摘要
为了量化高频机械振动对土壤液化的具体效果,在试验室泥槽中对不同性质的水下粉细砂沉积物开展了诸如不同振动作用时间及不同工况下的液化试验,利用静力触探仪测量了振动作用前后其承载力变化情况,基于试验数据分析讨论了振动作用时间、振动作用距离、振动频率对于液化效果的影响。
In order to quantify the specific effect of the soil liquefaction induced by high-frequency mechanical vibration on soil, a liquefaction test for various vibration effect durations under different operation conditions is made on the sediment consisting of under-water fine silt in lab ; in which the changes of the bearing capacities before and after the vibration are measured with static cone penetrometer, and then the effects from the vibration effect duration, vibration effect distance and vibration frequency on the soil liquefaction are discussed in accordance with the testing data concerned.
