摘　　要：源地上抗剪强度指标φ、C值对泥石流的发生具有重要意义,为探索源地上抗剪强度与主体含水量关系而做的主体φ、C值随含水量变化的试验表明,在源地土含水量达到塑限以前,φ值随含水量的变化不是线性的,而是主要呈上凸和下凹两种曲线形式;C值随含水量的变化基本上是单调上升的.It is important for debris flow initiation research to study the shear strength indices of φ and C. In order to determine the relation between the shear strength indices of φ and C and the moisture content Q, some geotechnical tests are made. The results show that be fore the Q value reaches the plasticity index, the φ value varies with convex and concave shapes as the Q value increases;C value increases as the Q value increases.
