摘要
针对董箐水电站面板堆石坝坝高150m，主要筑坝材料为砂泥岩（含软岩15％～35％）的特点，借鉴国内外面板堆石坝建设的最新成果和经验，进行面板坝接缝止水的设计，解决了含软岩料筑坝接缝变形可能大的难题。
According rock of 15% - 35% ） est achievements and with soft rock may be to the characteristics of 150m high CFRD with main materials of sand and clay （ including soft , the CFRD joint seal design is carried out by domestically and internationally utilizing the latexperiences of CFRD construction. The design solves the problem that the placing materials exoected to induce big dam ioint deformation.
