摘要
通过不同桩体加固液化土模型振动台试验,传感器采集的试验数据整理分析,探讨不同加固方式不同埋深处的孔隙水压力、土压力以及加速度的变化规律,得出碎石桩具有很好的消散孔隙水压力和挤密土体的作用,水泥土桩可以有效分担水平地震力。
Through different reinforcement model shaking table test of liquescent sand,and finishing,comparison and analysis of test data collected by sensor,the changing rule of excess pore water pressure,earth pressure and the soil layer acceleration of different reinforcement mode of liquescent sand in different buried deep can be explored. It is concluded that gravel pile has the very good dissipation of pore water pressure and soil compaction effect,and cement-soil pile can share the horizontal seismic force effectively.
