煤矿采动与地震波耦合作用下建筑物损伤分析

Structural Damage Analysis of Coal Mining and Seismic Wave Coupling

针对煤矿采动区建筑物的地震损伤演化过程尚不明晰这一问题,以损伤力学研究为基础,结合结构动力学以及地震工程学等相关理论,通过数值计算分析建筑物在地震作用下的损伤以及在采动地震联合作用下的动力响应值,建立煤矿采动区地震影响下的建筑物损伤判断依据模型。研究发现,在煤矿采动与地震联合作用下,建筑物在各个方面的动力响应值都远大于建筑物单独存在时的数值,以期此结论为今后地震损伤的研究奠定理论基础。

According to the coal mine seismic damage evolution process of buildings is not clear this problem, based on the damage mechanics research, combined with the structural dynamics and earthquake engineering and other related theories, through the numerical calculation of damage under earthquake and mining analysis of the building in the earthquake dynamic response under combined action, the establishment of coal mine mining the earthquake zone under the influence of the building damage judgment model. The study found that the mining and seismic joint action in coal mine,building the numerical value is greater than the building of individual existence. The dynamic response in all aspects, so this conclusion lays the theoretical foundation for future research on earthquake damage.
