摘　　要：结合沙牌碾压混凝土拱坝,采用整体结构模型试验,分别对设置周边应力释放缝加两条诱导缝、三条诱导缝、坝体不设缝三种方案进行了坝体的应力及变形特性、破坏形态、破坏过程及破坏机理的分析,从而得出了不同分缝形式下高碾压混凝土拱坝的结构特性。This paper gives a briefing that by means of structural model testing Shapai RCC arch dam with three different joint formation schemes--1) with a peripheral joint for stress release plus two inducing joints,2) with a peripheral joint plus three inducing joints & 3) without any joints--was studied to analyse the dam stresses & deflections,failure pattern,process & mechanism.Therefore structural behaviors of high RCC arch dam with different joint formation schemes were found out.
