三峡枢纽主体建筑物混凝土表面保护研究与应用

清水混凝土作为一种新兴的建筑表达形式和先进的装饰保护理念，主要应用于公共及市政建筑，用于大型水利枢纽建筑装饰保护尚无先例。三峡工程建设中，在广泛总结国内外工程经验的基础上，借鉴清水混凝土的外观设计理念，以重视混凝土施工质量控制，建筑物混凝土表面的适时修补，后期保护性处理作为长久保持三峡工程主体建筑结构本色的主要技术手段，对确保枢纽整体建筑效果起到了至关重要的作用。通过三峡枢纽建筑物表面清水混凝土保护的研究与应用，初步形成了系统而可操作的清水混凝土应用技术体系，为今后类似工程提供了可资借鉴的经验。

Research and application of concrete surface protection of main buildings of TGP

As a kind of new decorative and protection material,fair-faced concrete is mainly used in public and municipal buildings,but has not been applied in the building decoration and protection of large hydropower projects.In the construction of TGP,based on the idea of fair-faced concrete and related domestic and foreign experiences,the main technological means for permanently keeping the natural color of main buildings of TGP such as strict quality control of concrete construction,timely patching of concrete surface,later protective treatment,have played key roles in maintaining the overall architectural effect of TGP,which provides treasured experience for future similar water conservancy projects.
