【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]:In many cases, face rockfill dam has become the optimal dam type, but its design still depends on engineering experience to a large extent. At present, there are few literatures to study the behavior of face rockfill dam based on a large number of engineering examples. The construction information and character monitoring records of 87 face rockfill dams which have been built in the past 50 years are collected and counted. The characteristics of face rockfill dams are analyzed from the point of view of statistics. Based on the measured engineering data, the settlement of the dam top, the deflection and stress of the face slab, and the maximum settlement of the dam body at the time of completion are statistically analyzed and summarized. The effects of saturated state compressive strength, foundation characteristics, river valley shape and seepage flow on the dam behavior are discussed in detail. The results can further enhance the understanding of the characteristics of the face rockfill dam and provide guidance and reference for the design, construction and operation management of the face rockfill dam.
