摘要
通过研究国内已投入运行的典型面板堆石坝面板实测垂直缝开合度及周边缝开合度、剪切量、沉降量的量值范围、影响因素及变化规律,得出面板接缝实测变形的合理量值范围及可能影响因素,可对运行期面板接缝的安全监测提供有益指导。
By studying the measured vertical joint opening-closing degree,and peripheral joint opening-closing degree,sheare and settlement range,influencing factors and changing rules of typical CFRD put into operation in China,the reasonable range and possible influencing factors of measured deformation of face slab joint are obtained,which can provide useful guidance for the safety monitoring of face slab joint in operation period.
