摘　　要：以毛尔盖工程为例,对深厚覆盖层心墙堆石坝坝基河床灌浆观测廊道与两岸灌浆平洞结构缝的设计进行研究,在三维有限元分析和类似工程经验、教训的基础上,对结构缝位置、止水结构等进行了优化和改进,运行期监测结果表明:其基本达到了预期的效果,对后续类似工程设计、施工提供了一定的参考。Taking the Mao＇ergai project for an example,the paper conducted research into the design of deep overburden layer core wall rockfill dam foundation bed grouting observation corridor and the grouting adit structure joints.Based on three-dimensional finite element analysis and similar project experience and lessons,the structure of joint position and sealing structure were optimized and improved,the monitor results achieved the desired effect and provided reference for the similar engineering design and construction.
