我国早期建设的公路因交通量急剧增长而不得不进行改扩建,但改扩建工程的实施对高速公路的车辆通行往往有很大影响。保持高速公路本身的正常安全运营是改扩建工程的前提条件,也是改扩建工程设计中所必须考虑的基本原则。通过对清连一级公路改扩建工程施工期交通组织的分析探讨,提出了各种交通组织方案,为今后改扩建工程交通组织设计提供参考。
The early construction of roads in our country had to be expanded and expanded due to the rapid increase of traffic volume. However, the implementation of reconstruction and expansion projects often had a great impact on the traffic passing through expressways. Maintaining the normal safe operation of the expressway itself is a prerequisite for the expansion and expansion project and also the basic principle that must be considered in the design of the expansion and expansion project. Through the analysis and discussion of traffic organization during the construction and reconstruction of Qinglian Class I highway, various traffic organization schemes are put forward to provide reference for the design of traffic organization for reconstruction and expansion project in the future.
