不封闭交通背景下高速公路改扩建中的养护管理

Maintenance management in highway reconstruction and expansion in open traffic

不封闭交通实施高速公路改建扩容,其复杂多变的施工环境提高了养护管理的安全风险性。减少改扩建施工对养护管理的不利影响,保障施工状态下道路设施养护管理到位,保障道路安全畅通,以达到最初"边通车、边施工,边养护"的设计目标。

The complex and changeable construction environment of highway reconstruction and expansion in open traffic increases the safety risk of maintenance management.In order to achieve the original design goal of"While open to traffic,while construction,while maintenance",we need to reduce the negative impacts of reconstruction and expansion on maintenance management,ensure that road maintenance management is in place under construction conditions,and ensure the road safe and unimpeded,
