摘　　要：德厚水库右岸库区广泛发育的岩溶漏斗、落水洞等会导致水库内蓄水渗漏,影响水利工程的效益,帷幕灌浆是降低库区岩层渗透性的有效手段。灌浆试验采用分段灌浆工艺,结合灌浆参数和钻孔压水试验数据以及灌浆试验效果,得出最优的帷幕灌浆施工技术参数,为科学有效施工提供了技术支撑。试验结果表明,采用该帷幕灌浆施工达到了设计要求的防渗效果,可为同类复杂条件下水库工程帷幕灌浆提供参考。The widely developed karst funnels and sinkholes in the right bank area of Dehou Reservoir will lead to the reservoir water leakage,influencing the benefit of water conservancy project.Curtain grouting is an effective means to reduce the permeability of reservoir rock.The optimal curtain grouting construction technical parameters are obtained by using subsection grouting technology in grouting test,combining grouting parameters,borehole water pressure test data and grouting test results,which provides technical support for scientific and effective construction.The test results show that the curtain grouting has achieved the anti-seepage effect required by the design,which can provide reference value for the curtain grouting of reservoir project under similar complex conditions.
