摘　　要：由于工期紧、施工质量要求高,江坪河水电站面板堆石坝垫层区拟采用翻模固坡技术。在正式施工之前,对面板堆石坝进行数值模拟计算,预测堆石坝体在不同分期条件下的变形和应力,从而预留出合理的变形值,能够减少面板的开裂、脱空。Due to tight construction time and requirement of high construction quality,it is proposed to use turned-over formwork slope-fixing technology in the faced rockfill dam cushion zone of Jiangpinghe hydropower project.Before formal construction,numerical simulation calculation of faced rockfill dam is carried out so as to predict dam body deformation and stress under different staged conditions,and provide rational deformation values,which can reduce face cracks and voids.
