摘要

新建公路与既有公路交叉时,如遇既有公路路基填土高度较高,具备新建公路下穿既有公路条件时,可采用既有公路路基改桥梁方案。主要介绍了既有公路路基改桥梁方案的保通措施、上下部结构设计及施工工序等。
        When a new road route crosses an existing road route, the existing Subgrade can be changed into a bridge if the height of the existing Subgrade is relatively high and the conditions for the new road route undercrossing the existing road route are met. This paper mainly introduces the guaranteed access measures, superstructure and substructure design and construction procedure of the existing Subgrade being changed into a bridge.
