摘要
2013年7月10日,茂县南新镇白水寨沟暴发大型泥石流,泥石流冲毁沟内原有3道拦砂坝。受"5.12"汶川特大地震影响,沟内滑坡、崩塌等松散物源激增,可能参与泥石流活动的物源量为176.10×104 m3,是导致本次泥石流的主要原因。经调查研究,白水寨沟在强降雨条件下再次暴发大规模泥石流的可能性较大。
On July 10 th,2013,an large debris flow occurred in Baishuizhai gully of Nanxin town,Maoxian county China,which destroyed all the 3 sand dams.By the affect of"5.12"Wenchuan earthquake,the landslides in the gully,falls and other loose material sources surged.The source amount of dynamic reserves which maybe participate the activity of debris flow is up to 176.1×104 m3,which is the main cause of this debris flow.The investigation and researches show that the feasibility of debris flow happening in Baishuizhai gully in the condition of rainfall is large.
