为了探讨土—结构相互作用对煤矿采动损伤建筑地震动力破坏的影响,基于损伤力学和能量耗散理论,研究采动区土—基础—上部结构的协同作用,通过建立考虑土—结构相互作用的煤矿采动损伤建筑的动力学方程,重点分析了煤矿采动损害影响下的建筑物地震动力灾变演化过程。计算结果表明：土—结构的相互作用对煤矿采动建筑的地震动力响应影响较大,不考虑土—结构相互作用是偏于安全的;煤矿采动作用明显改变了建筑物的结构动力特性,建筑结构的薄弱层位置改变明显、塑性铰和层损伤分布规律发生改变,严重降低了建筑物的抗震性能,对于煤矿采动区建筑应当开展安全损伤评估工作,以保证矿区工程建设的安全性和可靠性。

英文摘要：

In order to discuss the influence of the soil-structure interaction on the seismic dynamic failure process of coal mining damaged building, based on damage mechanics and the energy dissipation theory, we study the synergetic effect of soil-foundation-superstructure in mining area. By establishing the dynamics equations of coal mining damaged buildings considering soil-structure interaction, we focus on study seismic dynamic disaster evolution process of the building under the influence of the coal mining damage. The calculation results show that the influence of soil-structure interaction on seismic dynamic response of the coal mining building is larger, without considering soil-structure interaction is safer. Due to coal mining, the structure dynamic characteristics of the building is changed, the position of weak layer of the structure changed significantly and the plastic hinge and the distribution law of layer damage changes, which all seriously reduce the seismic performance of the building. The safety damage assessment should be taken for the buildings in coal mining area, which could ensure the safety and reliability of mining engineering construction.
