摘要 为解决特高拱坝坝基加固与混凝土浇筑间相互影响、无盖重固结灌浆质量难以达标等难题,该文结合乌东德坝基固结灌浆工程,通过现场生产性试验研究,提出"表封闭、浅加密、深提压、严监控、少引管"的无盖重固结灌浆成套技术。该技术不仅消除了坝基固结灌浆与混凝土浇筑的干扰,还有效保障了无盖重固结灌浆质量。乌东德工程实践表明:声波测试一次合格率100%,灌后检查透水率全部达标,研究成果对混凝土拱坝和碾压混凝土重力坝坝基加固技术的进步和发展起到了积极的推进作用。

Abstract:This study analyzed the interactions between dam foundation reinforcement and concrete pouring for the foundations of high arch dams without a heavy cover to consolidate the grouting. This study used the Wudongde dam foundation grouting as an example without a heavy cover for the consolidation grouting using the "table closed, shallow encryption, booster, strict monitoring, and little tube" method. This method not only eliminates the interference between the dam foundation consolidation grouting and the concrete pouring, but also guarantees the quality of the non-capped consolidation grouting. The results from the Wudongde Hydropower Station show that the first pass rate of the acoustic wave test was 100% and the water permeability after irrigation met the standard.
