摘要
评价泥石流灾害危险性有助于选择合适的工程措施降低其危害程度。从汶马高速平桥沟的沟道地形、潜在物源、水源三个方面出发,分析泥石流形成条件,计算潜在冲出量,对其危险性进行评价。研究表明:平桥沟泥石流物质堵断梭磨河成灾的可能性较小,工程措施可行。
Evaluating the hazard of debris flow is helpful to select appropriate engineering measures and reduce its hazard degree.Starting from the three aspects of channel topography,potential material source and water source of Pingqiao gully of Wenma Expressway,the formation conditions of debris flow are analyzed,the potential discharge is calculated,and its risk is evaluated.The research shows that the possibility of blocking the Suomo River by debris flow in Pingqiao gully is small,and the engineering measures are feasible.This kind of evaluation research can provide reference for debris flow risk assessment in similar areas.
