中文摘要：
速流结构是公路泥石流防治体系中常用且有效的工程措施之一。文章基于底越式速流结构的受荷模式及边界条件,将汇流槽视为三次超静定梁,运用结构力学方法求解侧墙及嵌固桩的内力;将速流槽与嵌固桩引入Winkler模型,用弹性地基梁理论求解速流槽内力、位移及地基反力,由此提出底越式速流结构计算理论。以平川泥石流防治工程为例,进行内力计算。
英文摘要：
High-speed drainage structure is one of usual and effectual engineering measures for controlling debris flow in highway. Based on the modes of loads and the boundary conditions, converge pough was regarded as static-indeterminate beam. It introduced Winkler model to base-pass high speed drainage trough and anchor pile by using the means of elastic foundation beam. Moreover, calculating theory of base pass high-speed drainage structure was put forward. Taking the protection project of Pingchuan debris flow for example, the results showed the internal force of high-speed drainage structure.
