摘　　要：为了加强高面板堆石坝工程中挤压边墙、高趾墩和高趾墙等特殊结构体的安全监测,基于面板堆石坝安全监测设计资料,总结了特殊结构体在安全监测设计方面存在的不足和缺陷。通过收集整理国内包含高趾墩、高趾墙和挤压边墙等特殊结构体的高面板堆石坝数值分析成果,发掘特殊结构体的变形和应力应变规律,将特殊结构体的变形、应力应变及温度、接缝和渗流明确为安全监测设计重点;结合已有面板堆石坝工程的安全监测设计资料,构建了复杂条件下高面板堆石坝特殊结构体安全监测设计体系。该体系能够为在建和拟建的面板堆石坝特殊结构体安全监测设计提供科学的指导,全面提升面板堆石坝的安全监测水平。In order to enhance the safety monitoring of special structures such as extruded sidewalls,high toe piers,and high toe walls in a high panel rockfill dam project,the shortcomings and deficiencies in the safety monitoring design of these special structures are summarized based on the safety monitoring design data of panel rockfill dams.By gathering and organizing numerical analysis results of high concrete face rockfill dams with specialized structures of high toe piers,high toe walls,and extruded sidewalls in China,we unearthed the deformation and stress-strain laws of specialized structures.Furthermore,we identified deformation,stress-strain,temperature,joints,and seepage of specialized structures as the key points of safety monitoring design.Based on the safety monitoring design data of existing panel rockfill dam projects,we formulated a safety monitoring design system for the specialized structures of high panel rockfill dams.This system can provide scientific guidance for the safety monitoring design of specialized structures of under-construction and planned panel rockfill dams,thereby significantly enhancing the safety monitoring level of panel rockfill dams.
