- Abstract
In the history of the Daqing debris flow development zone on the right bank of Dadan River in Lijiang, the debris flow disaster occurred many times, resulting in the destruction of the farmlands near the valley and the destruction of the road and bridge, which seriously threatened the safety of the lives and property of the nearby villagers. On the basis of the field investigation and sampling laboratory test of the Daqing debris flow basin and the analysis of the local hydrological and topographic features, the source and fluid characteristics of the Daqing debris flow are studied. On this basis, the risk of debris flow is evaluated; the development trend is predicted and the related protective measures are put forward. The research shows that the main source of the Daqing debris flow development zone is the loose solid particles; the reserves are 260 thousand cubic meters and the dynamic characteristics are obvious; the debris flow is in the strong period of the eruption of debris flow. Under extreme rainstorm conditions, the risk of debris flow is 0.59, which is moderately dangerous. So scientific and effective precautions should be taken to reduce the damage to the villagers and roads in the basin caused by debris flow.
