本文所研究的泥石流,其特点在于固体迳流超饱和状态;即在水力作用之外还有重力作用。预报用于具有威胁生产和生活、且有严重潜在危险的泥石流。 预报的基础是以沟道系数(Ic) 为条件,遥测集水区内固体迳流最大供给量(M’max)和洪峰流量(Q)。遥测土体水分动态、土压、土体张力的变化,就可掌握水动压力的形成和变化。根据这些资料,结合泥石流的起动点和烈度的分析,就形成了长期监测,分区分级预报系统。 使用遥控摄像定时跟踪图示装置,可以提高预报的精度和质量。并于文中提出预报系统框图。
Debris flow studied in this paper is characterized by the supersaturation of solid 迳 flows; that is, there is gravity outside of the hydraulic action. Forecasts are for landslides that pose a threat to production and life and have serious potential hazards. The basis of the prediction is based on the channel coefficient (Ic), telemetry the maximum supply (M’max) and peak flow (Q) of solid 迳 flow in the catchment. Telemetry soil moisture dynamics, soil pressure, soil tension changes, you can master the hydrodynamic pressure of the formation and changes. Based on these data, combined with the analysis of the starting point and intensity of the debris flow, a long-term monitoring and zoning classification forecasting system has been formed. The use of remote camera timing tracking icon device, you can improve the accuracy and quality of the forecast. And in the text proposed forecast system block diagram.
