关于几种设计情况下道路建筑限界问题的探讨

Discussion on Boundary of Road Construction under Several Design Conditions

摘要:

结合施工图审查工作中遇到的具体案例，对“道路建筑限界内不得有任何物体侵入”这一强制性要求进行了论证，并重点分析了与道路建筑限界相关的横断面设计内容，包括在各种工程情况下安全带的正确设置以及有二次过街需求的中间岛设置等，以期对设计人员起到提醒的作用。

Abstract:

Based on the specific cases encountered in the review of construction drawings, the mandatory requirement of "no object intrusion within the limits of road construction" is demonstrated, and the cross section design related to the road construction limits is specially analyzed, including the correct setting of safety belts in various engineering situations and the setting of intermediate islands required for the secondary crossing in order to serve as a reminder to designers.
