【摘要】 震裂边坡在地震灾区分布较广,是规模较大的潜在灾害,其在雨水下渗等外界影响因素的作用下稳定性可能会发生较大的变化.针对不同的裂缝位置、裂缝深度以及考虑是否灌水,运用ABAQUS大型有限元软件,开展均质土震裂边坡的降雨稳定性分析.结果揭示了上述不同情况下的震裂边坡在降雨中的变形破坏和稳定性变化的规律,为类似边坡的分析评价及工程治理提供借鉴.更多还原

【Abstract】 Cracked slopes induced by an earthquake are potential disasters which widely distribute in the earthquake stricken area. The stability of these slopes subjected to rain infiltration will change greatly. In this paper,the variation of safety coefficient of homogeneous soil slopes with rainfall is calculated by ABAQUS for different crack positions,different crack depths and irrigations. The results reveal the law of deformation and stability of cracked slopes induced by earthquakes in rainfall conditions,providing a theoretical reference for evaluation and engineering protection of such cracked slopes.更多还原
