摘要
2012年7月7日巴中市河坝2井暴发较大规模山洪泥石流,严重影响了当地人民和井场的正常生产与生活。在现场调查泥石流灾害的基础上,对形成泥石流的地形、水源、物源进行了论述,分析了该泥石流的成因机制;计算了泥石流的动力学参数,针对现有物源及潜在泥石流隐患,提出了"主沟疏通+防洪堤支挡"的防治建议。
On July 6,2012,a large- scale debris flow attacked Heba Well 2 in Bazhong City,which seriously affected the normal production and living of the local people and the Well site. This paper,on the basis of field investigation on the debris flow disaster,firstly discussed the conditions forming the debris flow,including topography,water source and sediment source; meanwhile,analyzed the formation mechanism; then the dynamic parameters thereof were calculated. Combined with the existing provenance and potential hazards,the prevention suggestions of " main channel dredging + levees retaining" were proposed.
