摘要:2020年“8.11~8.12"强降雨后,白鹿镇关沟村6组爆发了泥石流。关沟泥石流造成挡拦坝及沟侧道路路基受损。通过前期资料收集、现场调查、特征值计算等方法对关沟泥石流灾害特征进行分析,结果表明:关沟泥石流属于暴雨沟谷型中高频粘性泥石流，易发程度属于易发性泥石流。最后,提出采用拦排结合的治理方式进行防治,减轻泥石流灾害。
Abstract: Afer heavy rainfal from August 1l to August 12 in 2020, a debris flow broke out in Group 6 of Guangou Village,BailuTown.The debris flow in Guangou has caused damage to the retaining dam and the roadbed on the side of the ditch.T'he characteristics ofdebris flow disasters in Guangou are analyzed by means of early data collection,field investigation, eigenvalue calculation and othermethods. The results show that the debris flow in Guangou belongs to the rainstorm gully type medium and high frequency viscous debrisflow, and the vulnerability degree belongs to the prone debris flow.Finally, it is proposed to use a combination of interception and drainagofor prevention and control to reduce debris flow disasters.
