| 摘 要： | 泥石流的淤积厚度是泥石流灾害评估和防治的最重要的参数之一,但迄今还没有较好的方法计算不同容重的泥石流淤积厚度。本文通过研究泥石流屈服应力的特点,提出了用地区参数和泥石流体积浓度来计算泥石流屈服应力,进而计算泥石流淤积厚度的方法。采用本文方法计算已发生泥石流地区不同容重泥石流的淤积厚度,可以很好地应用于泥石流灾害评估和防治。

| Abstract: | The deposit depth of debris flow is one of the most important parameters in the evaluation and prevention of debris flow.So far,there is no better method for deposit depth calculation of debris flow with different densities.In this paper the characteristics of yield stress of debris flow was studied and a method was proposed for the yield stress calculation using area parameters and volume concentration of debris flow.Base on the analysis of yield stress of debris flow,the deposit depth of debris flow can be obtained.This method can be used for the calculation of deposit depth of debris flows with different densities in debris flow areas.This work provides a better tool for the evaluation and prevention of debris flows. |
