摘　　要：各选取一种有机类和无机类典型压浆材料,在对大量试验数据统计分析基础上,总结动水冲刷作用下不同养护龄期压浆材料的强度水蚀率、质量损失率及体积收缩率三大性能指标的变化规律,然后分配动态权重系数综合计算上述指标,提出压浆材料冲刷系数指标。试验结果表明当冲刷次数较少(20 000次以内),宜选用无机压浆材料作为板底脱空的填补材料;当冲刷次数较多(20 000次以上),宜选用有机压浆材料作为板底脱空的填补材料。Experiments were conducted by choosing two groups of typical organic and inorganic grouting material,and summarizing the change regularities of the grouting material′ s three indexes including strength erosion rate,quality loss rate and volume contraction rate under different curing age and dynamic water scouring based on the statistical analysis of a large number of test data,then calculating these indexes distribution and put forward scour coefficient index of grouting material by using dynamic weight coefficient.The results show that it is recommended to use inorganic grouting materials as filling material of slab when scouring action times is less（less than 20 000）,and it is recommended to use organic grouting materials as filling material of slab when scouring action times is more（more than 20 000）.
