摘要
江垭大坝自１６４ｍ高程至２００ｍ高程采用ＲＣＣ斜层铺筑法施工。经坝体钻孔压水及取芯检查，ＲＣＣ的抗渗性及力学指标均满足设计要求。实践表明，ＲＣＣ斜层铺筑工艺有效地解决了大仓面施工中浇筑能力不足和入仓混凝土停放时间长的问题，加快了施工速度。
The Jiangya RCC dam of 164m￣200m level is constructed by slop layer paving method. Water pressure test and coring inspection in dam borehole indicated that RCC impermeability and mechanical property meet design demand. The practice shows that slop layer paving technology resolves effectively questions concerning concreting capacity not enough in large cast place and placing concrete long staying. This method can speed construction schedule and raise project quality.
