| 摘 要： | 推导了弹塑性介质应力应变本构关系公式,用构建弹塑性动力有限元模型研究青藏高原地壳运动。计算得到青藏高原地壳运动、应变及应力状态,对比应力、应变集中区域与强震分布的关系。结果表明,大部分强震发生区域与文中模型计算得到的地壳应力、应变集中区域重合。

| Abstract: | The constitutive formula of stress and strain is derived, and dynamic response finite element model of elastic-plastic medium is established to analyze the movement and stress change at Qinghai-Tibet Plateau crust. The states of movement, strain and stress at Qinghai-Tibet Plateau crust are calculated and compared to obtain the relationship between stress-strain and strong earthquake distributing. The results show that most of strong earthquake regions coincide with the results of model simulation. |
