摘　　要：天然建筑材料勘察评价是水电工程地质勘察工作的重要内容,关系到坝型选择、施工进度与大坝运行安全。近年水电工程建设中常遇到防渗土料、堆石料、混凝土骨料等天然建筑材料质量无法满足设计要求,但经采取针对性料源改性或工程处理方案后,可满足筑坝材料需求的工程案例。结合多座大型水电工程建设经验,总结土料、石料勘察评价工作要点,探讨相应料源改性或工程处理思路,并提出天然建筑材料选择中的几个关注点。The investigation and evaluation of natural construction materials is an important part of the geological investigation of hydropower engineering,which is closely related to dam type selection,construction progress and dam operation safety.In recent years,it is common to encounter natural construction materials such as impermeable soil materials,embankment materials and concrete aggregate that fail to meet design requirements in hydropower engineering.However,these materials can be modified or treated to meet the requirements of dam construction after taking targeted measures.Based on the construction experiences of some large-scale hydropower projects,this paper summarizes the key points of the investigation and evaluation of soil and stone materials,discusses the modification or engineering treatment methods of these natural construction materials,and proposes several concerns in the selection of natural construction materials.
