公路特大型泥石流灾害控制技术研究

公路特大型泥石流是国内外迄今尚未解决的主要公路病害，具有大冲大淤、冲击路径变化不确定以及毁损作用极其强烈的特性，是公路泥石流研究及防治的核心。本文基于两相流理论建立了泥石流冲击力计算公式；遵循特大型泥石流发育特点及公路泥石流防治特殊要求建构了泥石流综合治理模式，并开发了速流结构、底埋隧道、翼型墩汇流技术及糙桩技术，并对相关的核心技术进行了深入分析。研究成果对于彻底解决公路特大型泥石流病害奠定了重要的技术基础。

Research on Countermeasures for Giant Debris Flow Disaster Along Highways

As one of main disasters is not controlled hitherto in the world, giant debris flow along highways show many features such as strong impact, giant deposit, various impact routes and damage to highway, which must be the key object both in research and prevention of debris flow along highways. The impact formulas in two-phases theory are established in this paper. According to the develop features of the debris flow and special ideas of debris flow counter along highway, the synthetical model to control giant debris flow are built, and the developed four effective, countermeasures, high-speed drainage structure, submerge structure, converge technique of wing-shaped pier and piles arrangement to counter the debris flow are developed, then some relative key techniques to these countermeasures are approached. Results lay an important technique foundation to control effectively giant debris flow along highways.
