| 摘 要： | 速流结构是治理公路大型泥石流的有效技术类型,由汇流槽和速流槽组成.汇流槽在泥石流冲击作用下的受荷性能是速流结构应用的关键技术之一,本文建立了汇流槽板质量-阻尼-弹簧动力学模型,据此运用结构动力学方法构建了汇流槽板的挠曲线方程和动力学方程,为汇流槽板结构强度设计及变位控制设计提供了依据,其成果于平川泥石流防治工程中得到成功应用.

| Abstract: | As one of the most effective techniques to control giant debris flow,the High-speed drainage structure is composed of both converge trough structure and high-speed drain trough structure.Especially,mechanical features of converge trough under impact of debris flow is the key technique in the High-speed drainage structure application.Mass-damp-spring dynamic model of the converge trough plate is established in this paper,further both deflection equation and dynamic equation of the converge trough are founded in structure mechanics theories,which set up basis for structure strength design and deformation design of the plate.Research results are in effective application in Pingchuan debris flow. |
