摘　　要：中国地震动参数区划图调整使卡拉贝利水利枢纽大坝在校核地震工况条件下,局部抗震稳定不再满足现行规范要求,必须对大坝采取抗震加固措施。本文就卡拉贝利大坝抗震加固技术进行研究论证,现场试验结果显示:选定的坝体控制灌浆工艺、套阀管灌浆工法符合大坝现状条件,确定的控制灌浆范围和施工参数安全可靠性高、经济适用性好,大坝经灌浆处理后可以满足抗震稳定要求。The adjustment of China’s seismic parameter zoning map led to the Kalabeili Water Conservancy Hub Dam not meeting the current normative requirements for seismic stability under the conditions of a check earthquake.Therefore,seismic reinforcement measures had to be taken for the dam.This paper conducts a study and demonstration on the seismic reinforcement technology for the Kalabeili Dam.The results of on-site experiments show that the selected dam body control grouting process and sleeve-valve pipe grouting method are suitable for the current conditions of the dam.The determined control grouting range and construction parameters have high safety reliability and economic applicability.The dam,after grouting treatment,can meet the requirements for seismic stability.
