沥青心墙砼坝一二期接头型式研究与运用

Research and application of joint type of first and second phase of asphaltconcrete core wall dam

目前国内碾压沥青混凝土心墙分一、二期施工的工程多采用扩大接头型式,且已在国内工程中得到应用。其他接头型式在工程中尚未采用,旁多工程采用包裹式接头型式,需开展包裹式接头型式专项研究,其试验过程、经验及效果值得同类工程借鉴。

At present,the expand joint types always be used in rolled asphalt concrete core wall in China which includes one phase and two phase construction,and has been applied in domestic engineering.Other connectortypes in the project has not yet adopted;Pangduo project using wrap-joint type,need to carry out special research wrap-joint type;its testing process,experience and results can be reference for the similar projects.
