中文摘要：
结合武广客运专线红粘土直剪实验结果,按照固结快剪、快剪和慢剪3种实验条件,分别计算红黏土粘聚力、摩擦角、含水率以及液塑限等常规物理指标之间的Pearson相关系数和显著性概率,对显著影响因子的作用机理进行分析。通过分析得到了不同剪切条件下红黏土粘聚力和摩擦角的主要影响指标及其作用机理、粘聚力随液性指数的变化规律以及抗剪强度的统计结果。
英文摘要：
Based on the data from three types （UU, CU and CD） of red clay direct shear text of Wu - Guang passenger transportation line, the Pearson correlation coefficients between cohesion, friction angle and other physical indexes were calculated separately, and corresponding significance probability was calculated, the mechanism of the significance influence factors was analyzed. The major influence indexes and their mechanisms were obtained. The variation regularity of cohesion and liquidity index and the statistic result of shear strength were obtained .
