双家沟泥石流特征及防治措施研究

Study on Characteristics and Prevention Measures of Debris Flow in Shuangjiagou

泥石流具有爆发突然、来势迅猛、破坏性极大等特点,一旦发生将给工程建筑设施带来巨大威胁。双家沟为一条较为活跃的泥石流沟,通过现场踏勘、区域资料收集、室内试验,分析总结双家沟泥石流的发育特征,计算相关的动力学特征参数,包括泥石流的容重、流速、流量及一次泥石流总量,据此对泥石流的易发性进行评价。研究表明:双家沟属于轻度易发性泥石流沟,为中频稀性泥石流,现状处于泥石流的发展期,需采取相应的防治措施。

Debris flow has the characteristics of sudden eruption,rapid and destructive force.Once they happen,they will being great threat to the construction facilities.Shuangjiagou is an active debris flow fully,through the field survey,regional data collection and indoor tests,this paper analyzes and summarizes the development characteristics of debris flow in Shuangjiagou,and calculates the relevant dynamic characteristic parameters,including the unit weight,flow rate,flow rate and the total amount of debris flow at one time,so as to evaluate the vulnerability of debris flow.The research shows that Shuangjiagou is a slightly prone debris flow gully,a medium-frequency rare debris flow,which is now in the development period of debris flow,and needs corresponding prevention and control measures.
