摘　　要：在内蒙古前夭子水库右岸库区防渗堵漏施工中,地层结构主要为"三岩三土",岩层整体风化破碎、垂直裂隙发育;个别部位地层复杂,渗漏严重,通过对玄武岩夹层复杂地层分析,总结出一套针对玄武岩夹层的灌浆施工技术,以便提高施工质量、加快施工进度、降低施工成本和工程造价。In construction of impermeability and seepage blocking on right bank of Qianyaozi reservoir, Inner Mongolia, the stratum teatures rock mass tectonics with soil filled. The stratum is weathered and fractured wholly. The vertical fractures are developed. The stratum in some positions is complicated and seepage is serious accordingly. Through analysis on the complicated stratum of the basah interlayer, a set of technology on grouting in the basalt interlayer is explored to improve construction quality, expedite construction progress and decrease construction cost and project investment.
