青岛海湾大桥桥梁混凝土耐久性设计方案研究

Study on Concrete Durability Design Scheme for Qingdao Trans-bay Bridge

详细说明了影响桥梁混凝土耐久性的因素及如何通过设计提高混凝土的耐久性。针对青岛海湾大桥的特定环境条件提出其混凝土耐久性设计方案应为合理的保护层厚度和高性能混凝土技术附加混凝土表面保护和阴极保护技术的综合设计方案。

In this paper, the factors affecting the bridge concrete durability and the design methods for improving the concrete durability are expounded. In consideration of the specific environment conditions, the bridge concrete durability design scheme is proposed as an integrated design scheme to combine the reasonable protection layer thickness and high performance concrete technique with the concrete surface protection and cathodic protection technique.
