摘    要:本文首先建议了判别土质心墙坝地震裂缝的应力与变形判据。然后,运用“南水”双屈服静力弹塑性数值模型及等价粘弹性动力模型,结合瀑布沟高心墙堆石坝进行了6种方案的静、动力应力应变计算。对该坝产生地震裂缝的可能性提出了判断分析。在此基础上,提出了高土石坝地震裂缝分析方法与抗裂措施。

关 键 词:心墙堆石坝,裂缝,地震,抗裂措施,数值分析

Abstract:In this paper, the criteria of stress and deformation are proposed to judge the crack of high earth-rockfill dam. The static and dynamic numerical analysis of six design schemes for Pubugou dam, which is one of the highest earth-rockfill dam in China, are carried out by means of elastoplastic and equivalent viscoelastic constitutive model. Moreover, the possibility of crack induced by earthquake is discussed. Finally, the crack analysis method and anti-crack measures are suggested for the high rockfill dam.
Keywords:rockfill dam with core  crack  earthquake  anti-crack measure  numerical analysis
