典型沟谷型泥石流动力学特性研究——以湖北省罗田县天堂寨老寺庙泥石流为例

Study on Flow Dynamics Characteristics of Typical Valley Debris

以罗田县天堂寨老寺庙泥石流为例,通过收集泥石流区域地质资料,经过专业技术人员实地勘查,参考相关的规程、规范和技术要求,计算出泥石流的一次总量、撞击力、泥石流中石块运动速度等一系列参数,揭示泥石流的成灾机理、发育规律及沟谷型泥石流的动力学特性,为泥石流的防治措施提供重要依据。

Taking the old temple debris flow in Tiantangzhai of Luotian County as an example,through collecting the regional geological data of debris flow,through the field investigation of professional technicians and referring to the relevant regulations,specifications and technical requirements,a series of parameters such as the total amount of debris flow,the impact force and the speed of rock movement in debris flow are calculated,and the disaster mechanism,development law and gully type debris flow are revealed.The dynamic characteristics of debris flow provides an important basis for debris flow control measures.
