摘要
目前,对于公路下穿式立交引道U形封闭式路堑(以下简称封闭式路堑)设计,还没有一种公认的成熟的设计方法加以推广使用,采用分类归纳的方法,结合实际设计过程中的经验,优化封闭式路堑的设计模型及参数。针对封闭式路堑设计存在的现状问题,通过对封闭式路堑的设计理论和方法进行研究,合理选取计算模型和设计参数,优化了封闭式路堑的设计方法。
At present,U-type closed road cutting approach（hereafter abbreviated as closed road cutting） design for the interchange of highways,has not been recognized as the mature design method for wide application.This paper adoptes inductive classification method,incorporating practical experience in the design process to optimize the design of closed road cutting model and parameters.In view of the current problems existing in the design of closed road cutting,through the study on design theory and methods,reasonable models and design parameters are selected to optimize the design.
