基于监测数据的水布垭面板堆石坝变形控制技术分析

Analysis on deformation control technology of Shuibuya concrete face rockfill dam based on monitoring data

水布垭工程是中国面板坝建设技术领先于世界的标志性工程,运行至今已产生了显著的经济效益。介绍了水布垭大坝变形控制技术创新,主要包括坝料分区设计、大坝填筑程序、基础处理、坝体填筑质量实时监控等。分析水库蓄水后13 a的实测资料表明,大坝变形性态良好,变形控制技术科学有效。这些技术成就对后续高面板坝建设具有良好的示范与借鉴作用。

Shuibuya Hydropower Station is the world-leading landmark project in the field of the construction of concrete face rockfill dam(CFRD).So far,the project has created significant economic benefits.This paper introduces the innovation of dam deformation control technologies such as the design of dam material partition,the dam filling procedure,the dam foundation treatment,the real-time monitoring and control of filling quality.In addition,the rationality of these deformation control technologies is verified by analyzing the 13 years monitoring data since the reservoir impoundment.The results show that the deformation status of Shuibuya CFRD is in good condition and the dam deformation control is scientific and effective.These technical innovations provide a good example and reference for the construction of high CFRD.
