摘　　要：西藏地区地理位置独特,水文地质气候条件复杂,自然环境恶劣,造成该区域内水利工程施工和运行条件恶劣,且西部水利工程一般规模大、泄洪建筑物受高速含砂石冲刷严重。鉴于西藏水利工程劣化防护措施缺乏,相关劣化防护规程规范和技术标准研究滞后,可供借鉴的经验较少,结合西藏地区水利工程劣化现状调查报告,对多种劣化形式的演变过程和机理进行分析,并详细介绍了当前劣化防护的新材料、新技术、新工艺及其研究进展,提出了适用于西藏地区水工建筑物防护的几种方案措施,及相关防护材料的性能需求及进一步的研究方向。As the unique geographic position, complex hydro-geological and climatic conditions, and harsh natural environment, the water conservancy project construction and operating environment in Tibet are poor. Moreover, the water conservancy projects in Western China usually have large scale in general and are scoured by high-speed sandstones. In view of the lacks on the protective measures of water conservancy projects, the regulations and technical standards related to the deterioration and the protection experiences in Tibet, the evolution courses and mechanisms of deterioration are analyzed based on the survey of water conservancy project deterioration in Tibet. The researches on new materials, technologies and treatment processes of deterioration protection are introduced, and some protection measures for water conservancy projects in Tibet are proposed. The further research directions are also proposed on the performances of protection materials.
