摘要
在分析天生桥一级和阿瓜密尔帕两座200 m级高混凝土面板堆石坝出现工程问题的原因的基础上,指出目前坝体分区设计原则的不完全性,提出了面板堆石坝坝体分区设计新理念,即坝体分区设计除了遵循料源决定原则,水力过渡原则和开挖料利用原则以外,更要重视变形协调原则,提出了实现变形协调的4个途径,来确保高混凝土面板堆石坝的应力变形性状良好与大坝安全。
Based on an analysis of reasons for the problems occurred at Tianshengqiao First Dam and Aguamilpa Dam,200m high concrete face rockfill dams, the imperfection of current idea of dam zoning design has been indicated. A new concept of dam zoning for high CFRD has been put forward here.Deformation harmonization principle should be follwed,besides material resource principle,hydraulic transition principle and excavated material utilization principle in CFRD dam zoning design.Four ways for achieving the deformation harmonization have been put forward in order to make the stress-deformation behavior of high CFRD good and ensure dam safety.
