泥石流松散固体物质临界集聚量估算模型研究

松散固体物质是泥石流形成的重要物质基础。本文根据国内外主要试验场的泥石流观测资料，讨论了泥石流流量，输沙量及其与沟床纵坡，岩性之间的关系。并反演建立了松散固体物质临界集聚量Ｖ的估算的模型，最后给出了一个实际计算结果。

An Estimation Model for Critical Accumulation of Porous Solid Mass in Debris Flow Study

Porous solid mass is an important material base in the formation of debris flow.On the basis of the observation information about debris flow in the main test fields at home and abroad,the relationship among the rate of debris flow,the slope and the lithological characters is discussed,and an estimation model for critical accumulation of porous solid mass is established by reversal development.Satisfactory results are obtained in applying the model to the estimation about typecal debris flow gulley.
