摘　　要：堆石坝体是保证面板坝运行安全的主体,除限渗和排水作用外,限制蓄水后的变形是核心。水压力引起堆石坝体变形,面板承受它与堆石坝体接触面的切向力,使面板适应堆石坝体变形,并产生压应变。为使面板应变受控,必须控制蓄水后堆石坝体的变形。根据建坝实践中积累的经验教训,建议了控制蓄水后堆石坝体变形的标准,提出控制变形应考虑的主要因素。同时指出室内试验成果尚无法真实反应堆石料的变形特性,理论计算结果不能指导控制堆石坝体变形,靠经验方法、逐渐修改、完善控制变形的措施,定能控制高坝堆石坝体的变形,避免面板局部破损。The rockfill dam body is the main body that ensures the safe operation of the panel dam.In addition to limiting seepage and drainage,limiting deformation after water storage is the core.The water pressure causes deformation of the rockfill dam body,and the panel bears the tangential force on its contact surface with the rockfill dam body,making the panel adapt to the deformation of the rockfill dam body and generating compressive strain.In order to control the strain of the panel,it is necessary to control the deformation of the stone dam body after water storage.Based on the accumulated experience and lessons in dam construction practice,it is suggested to establish standards for controlling the deformation of the dam body after water storage,and to propose the main factors that should be considered in controlling deformation.At the same time,it is pointed out that the indoor test results cannot truly reflect the deformation characteristics of the reactor stone material,and the theoretical calculation results cannot guide the control of the deformation of the stone dam body.By relying on empirical methods,gradually modifying and improving the measures to control deformation,the deformation of the high dam stone dam body can be controlled,and local damage to the panel can be avoided.
