摘要
泥石流发生、发展，受构造应力和自重应力及水动力条件的控制和制约。斜坡应力的极限平衡不仅受斜坡坡度的影响，还受临界含水量的控制。故泥石流发生、发展的规模和频率不仅与现代构造运动强度和频率有关，还与斜坡应力的各相关因素有关。
The occurrence and development of debris flow is controlled by structural stress, self weight stress and water dynamic condition.The ultimate equilibrium of slope stress is affected by slope gradient,and also controlled by critic water content,so the occurrence of debris flow,and the seope and frequency of its development is not only related to intensity and frequency of modern structure,but also related the interrelated factor of slope stress.
