浅析定西市漳县石川乡赵家庄灶爷沟泥石流灾害成因

Analysis on the Causes of Debris Flow Disaster in Zaoye Gully, Zhaojiazhuang, Shichuan Township, Zhang County, Dingxi City

2016年6月,灶爷沟范围内发生了大规模的泥石流灾害,造成了高达800余万元的损失,威胁数千村民的生命安全,并且冲毁了原设在沟道内的泥石流监测设备。通过研究区域内地质、岩体岩性及该泥石流灾害的发生过程及结果,结合实地勘察和走访调查分析,可以判断本次泥石流灾害属于水力类泥石流,受地表径流影响较大。基于本次泥石流灾害,本文从泥石流灾害发生的成因,过程和结果等方面分别提出相应的防灾减灾建议,研究结果对水力类泥石流成灾过程的认识和研究具有一定的参考价值。

In June 2016,a large-scale debris flow disaster occurred in the area of Zaoyegou,causing a loss of more than 8 million yuan,threatening the lives of thousands of villagers,and destroying the debris flow monitoring equipment originally installed in the channel.By studying the geology,rock mass lithology in the area,and the occurrence process and results of the debris flow disaster,combined with on-the-spot investigation and visit survey analysis,it can be judged that this debris flow disaster belongs to hydraulic debris flow,which is greatly affected by surface runoff.Based on this debris flow disaster,this paper puts forward corresponding disaster prevention and mitigation suggestions from the causes,processes and results of debris flow disasters.The research results have certain reference value for understanding and researching the process of hydraulic debris flow disasters.
