摘要(Abstract)：

为保证滑坡上居民的生命和财产安全，揭示滑坡上砌体房屋的变形破坏规律，开展滑坡作用下砌体房屋的变形破坏过程模拟研究十分必要。试验基于ABAQUS接触分离式建模方法建立了砌体房屋精细化模型，利用黏性接触界面来模拟砂浆在墙体中的作用，并将数值模拟结果与物理模型试验结果进行了对比分析。结果表明：通过物理模型试验和数值模型试验中砌体房屋宏观变形特征及微观应力应变数据的对比，物理模型试验和数值模型试验的载荷-应变曲线拟合度较好、应变云图基本一致，证明了该数值模拟方法的有效性；揭示了滑坡张拉变形区房屋墙体裂缝的扩展规律和应变分布规律。研究结果可以为滑坡张拉区砌体房屋防护设计提供依据。
