The present study is aimed to address the rheological properties of viscous debris flow at low shear rate. It is found that overstress effect and shear-rate-thinning phenomenon characterize the viscous debris flow in the Jiangjia Ravine, China. Results obtained from this study are believed to lay the foundation for further study on the theory of debris flow rheology. 关 键 词：VISCOUS DEBRIS flow, Overstress, Shear-rate-thinning
