泥石流排导槽冲淤规律观察研究

泥石流排导槽是泥石流治理的一项重要工程措施，昆明以黑水河排导槽为重点，结合省内外有关沟域排导槽工程观测情况展开对排导槽冲淤规律分析研究。采用理论推导结合实际分析、各类型排导槽的应用通守优化分析，建立模型，找出其内在联系及适用范围，为泥石流排导槽的设计及推广应用确定了科学依据。

Study on Scouring and Deposition Laws of Debris Flow Drainage Trough

Debris flow drainage trough is a major engineering measure to control debris flow.The drainage trough of the Heishui River is taken for emphasis combined with relevant drainage trough survey, in provincial or out, the scouring and deposition laws of drainage trough were analyzed and researched.A model was established and its internal relationship and scope of application were found out by using theoretical deduction combined with actual analysis and the optimized analysis of all types of drainage troughs, which lays a scientific foundation for its design, populari zation and application.
