泸定水电站大坝在施工过程中却遇到了廊道混凝土浇筑和坝体填筑相互干扰、廊道施工进度滞后影响坝体填筑速度、上下游坝料穿越心墙防渗体运输、如何保证坝体临时断面提前上升而不影响施工质量等特殊问题.通过采取合理进行施工布置、分区填筑、铺设穿越防渗体的临时道路、削坡法进行接缝处理等技术措施,很好地解决了这些问题,确保了大坝安全度汛、按期蓄水,保证了大坝工程进度、质量、效益达标.%Some special issues are encountered in the construction of Luding Dam, including the interference of gallery concrete pouring and dam filling, the dam filling being delayed by gallery construction, upstream and downstream impervious material transport through core wall, and how to ensure the quality of construction not affecting by the temporary rise of some dam section.
