摘要
Zhaojia gully is located at northwest side of Pingshang Village of Leigu Town, Beichuan County, Sichuan Province, China, which was heavily hit by Wenchuan earthquake. By on-site field survey and laboratory analysis, this paper studied the developing conditions of debris flow, including geological and geomorphologic conditions, sediments source conditions, and rainfall conditions. The analysis shows that because of earthquake induced solid material, the frequency and magnitude of the debris flow and its hazard will increase greatly, which is the most significant feature of post-earthquake debris flow.
