| 摘 要： | 根据卫星遥感图像特征,分析了河北省太行山区复杂沟系泥石流的运动及动力学特征,提出了泥石流在支沟中是匀变速(加速)运动,在主沟中是脉冲式运动。阐述了主沟中的脉冲式运动方式是由泥石流能量(动力)积累与释放交替演变的结果,而能量的积累与释放是由主沟两侧地质环境条件所决定的

| Abstract: | On the basis of remote sensing image, the feature of kinematics and dynamics of mudflow in complex valley is analyzed in this paper. The author thinks that the movement state of mudflow in a minor valley is unform motion, and pulse form in a main valley. This movement state of mudflow in a valley is from the accumulation and release of the motion energy of mudflow itself. The accumulation and release of motion enetgy are determined from the conditions of geological environment of main valley sides. |
