舟曲县是甘肃省地质灾害较为严重的地区之一。在充分研究区域自然地质环境资料的基础上,本文根据舟曲县地质灾害调查与区划项目野外调查成果资料,全面阐述了全县不良地质现象发育类型对泥石流灾害的形成提供能量和物源,并通过对瓜咱沟的地形条件以及区内已有的泥石流物源的调查给出“排导+拦挡”的防治方案,对治理效果进行前期的效果分析,以期为区域地质灾害防治提供依据。
Zhouqu County is one of the more serious geological disasters in Gansu Province. On the basis of fully studying the data of natural geologic environment in the region, this paper comprehensively expounded the types of unfavorable geological phenomena in the county to provide energy and source for the formation of debris flow disaster based on the data of the field survey of the regional geological disaster investigation and zoning project in Zhouqu County. Through the investigation of the terrain condition of Guazhagou and the provenance of debris flow in the area, the prevention and cure plan of “Drainage + Blocking” was given and the effect of pre-treatment on the treatment effect was analyzed in order to provide the basis for the prevention and control of regional geological disasters .
