摘要

摘要: 在很多情况下面板堆石坝已经成为优选坝型,但其设计很大程度上仍然依赖于工程经验。目前很少有文献基于大量工程实例数据对面板堆石坝的性状展开研究。收集和统计过去50 a已建的87个面板堆石坝的建设信息和性状监测记录,从统计学的角度分析面板坝性状特征。基于工程实测数据对填筑完工后坝顶沉降、面板挠度和应力、竣工时坝体最大沉降进行统计分析和规律总结。重点讨论了堆石母岩饱和状态抗压强度、地基特性、河谷形状和渗流对大坝性状的影响。结果可以进一步加强对面板堆石坝性状的深入理解,同时为面板堆石坝的设计、施工和运行管理提供指导和参考。

Abstract: The concrete face rockfill dam (CFRD) has become a preferred dam type, yet its design is still largely based on the past experience. However, few studies have been conducted on the behavior of CFRDs on the basis of reliable case history data. A compendium of monitoring records and construction details of 87 case histories of in-service CFRDs constructed in the past 50 years is collected for analyzing the behavior of CFRD from the perspective of statistical analysis. The post-construction crest settlement, deflection and stress of face slab and the maximum settlement at completion time are analyzed. The effects of intact rockfill strength, foundation characteristics, valley shape and seepage flow on behavior of dams are discussed. A summary of the findings from the case histories is put forwrd to enhance the understanding of behavior of CFRDs. These results may help guide the design, construction and operation of CFRDs.
