都江堰八一沟8·13泥石流的形成条件分析
Initiation Conditions for the 8·13 Debris Flows in Bayi Gully of Dujiangyan
摘要
Abstract
The large number of collapse and landslide triggered by the 2008 Wenchuan earthquake had caused a lot of casualties.After the earthquake,the deposits from the collapse and landslide became the primary source for debris flows,which greatly increased the occurrence of earthquake-induced hazards.In order to carry out the hazards prevention work,this paper selected the 8.13 debris flows in the Bayi Gully as the example to investigate its initiation conditions.Field investigation and remote sensingmeasures were used,and three fundamental conditions to initiate the debris flows were analyzed including landform,soil source,and water source.The results suggested the initiation conditions were favor for the occurrence of debris flows.Additionally,theanalytical method applied in this paper can provide references for the study of debris flows under similar conditions.关键词
