【摘要】 随着混凝土面板堆石坝高度的逐渐增加,大坝堆石体的后期变形以及窄河谷内堆石体拱效应对大坝面板的变形和应力的影响愈发显著,致使河床中部的面板混凝土出现了不同程度的挤压破坏现象。分析面板混凝土挤压破坏的原因,并结合马来西亚巴贡混凝土面板堆石坝设计和施工状况,提出了一些预防措施,供大家探讨。更多还原

【Abstract】 With increasing height of concrete face rockfill dam,the deformation and stress effects on dam face slab are gradually predominant due to subsequent deformation of dam rockfill and arching effect of rockfill within narrow valley,which has given rise to extruding failures to some extent. Combined with design and construction of Bakun concrete face rockfill dam,the reason of extruding failures is analyzed,and preventive measures are brought up.更多还原
