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。
In many cases, the panel rockfill dam has become the preferred type of dam, but its design still relies heavily on engineering experience. Few literatures have studied the properties of CFRD based on a large number of engineering data. Collecting and counting records of the construction information and traits of the 87 CFR dams that have been constructed in the past 50 years and analyzing the characteristics of the dams of the dam from a statistical point of view. Based on the measured data, the statistical analysis and regular summary of the dam settlement, the deflection and the stress of the dam, the maximum settlement of the dam upon completion are completed. This paper mainly discusses the influence of the compressive strength, the foundation characteristics, the shape of the river valley and the seepage on the dam properties under the saturation state of the rockfill rock. The results can further strengthen the understanding of the properties of CFRD and provide guidance and reference for the design, construction and operation management of CFRD.
