摘要
通过室内承载板试验测试某地重塑黄土土样在不同压实度与含水量状态下的回弹模量,探讨回弹模量与两者之间的关系。同时,利用压力板仪测定土样的土-水特征曲线,进一步分析基质吸力对回弹模量的影响。
This paper tests the rebounding modulus of remolded loess sample in a certain place under different compaction densities and water contents via the indoor loading plate test and probes the relationship between the rebounding modulus and above two factors. Meanwhile the paper also adopts the pressboard gauge to determine the soil- water characteristic curves of the soil sample, and furthermore analyses the impact of soil base suction on the rebounding modulus.
