在分析崩滑坡面泥石流的基本特征和其峰值流速流量一般规律的基础上，以康定雅拉河无名沟1995年的百年一遇泥石流为研究示范，在了解该流域的基本特征，分析该次泥石流的形成，容重、颗粒组成等基本特性的基础上，用弯道超高的理论和用古乡沟泥石流建立的流速计算公式，计算测量断面的流速及泥石流峰值流速沿程变化，用形态调查法分析计算不同断面的泥石流流量，并分析其沿程变化，通过分析可知崩滑坡面泥石流峰值流速与流量在整个流通过程是逐步变化的，在靠近物源区，流量随着物源的加入逐步增加，而流速随着能量的消耗逐渐减少，在靠近堆积区由于坡降的减小，流速与流量呈减小的趋势，崩滑坡面泥石流峰值流速泥石流流速也有一个相对的匀速段，但这个匀速段的长度较短，崩滑坡面泥石流峰值流量过程的沿程变化曲线接近于正态分布，此类泥石流防治中的拦挡措施要注意充分利用其在坡降减小的过程中流速和流量迅速降低的特征，而其排导措施要注意到此类泥石流的高阻力特征，注意保证排导槽的足够坡度。

On the basis of analyzing general characters of slope debris flow triggered by landslides or collapses, the authors apply the debris flow of 1995 in Wuming gully as a model, which occurs a time in a hundred years. Then the basin characters, debris flow density, composition, velocity formulae are chosen. The formulae are based on Guxiang valley debris flow observation and curve bend supper high principles. Thus, the discharge formula is also obtained and used to calculate the discharge on different sections. From the data, the changing process of the velocity and discharge along the channel is gotten. From the process, it is known that the maximal velocity decreases down the slope channel. Near the triggered area, as rich deposits add in, a lot of kinetic energy of the debris flow is consumed and debris flow velocity slows down. Besides, near the sedimentary fan, the velocity drops with the slope goes down. The discharge increases at beginning sector with deposits are triggered and decreases with the slope goes down and some earth deposits. Through the whole research, the authors conclude that for the slope debris flow, the velocity appears stable in middle short sector. The discharge process looks like normal distribution. For the debris flow protection engineering, it is necessary to check the velocity and discharge decrease process of debris flow. And for the debris flow drainage channel building, it is important to know the high resistance principle of slope debris flow.
