ADINA在矿震对建筑影响分析中的应用

文章介绍了矿震相关知识与结构地震响应分析理论。根据抚顺老虎台矿1995~2003年的矿震监测数据,针对矿区附近一栋七层砖混结构住宅进行了矿震响应分析。应用ADINA软件模拟了矿震对建筑结构的作用,将分析结果以剪力图、弯矩图及结点位移时间函数形式显示在图中。结果表明,在近些年频繁的矿震作用下,抚顺地区矿震对砖混结构影响较大,未来几年内结构的累积损伤有加大趋势,应及时进行加固以免造成较大的损失。该研究方法可用来模拟矿震对建筑结构的作用,对今后预测矿震对建筑结构的影响程度研究具有一定的参考价值。

Application of ADINA in analysis of mining-induced earthquake effect on building

The mining-induced earthquake related knowledge and the theory of seismic response analyses of structure are introduced.According to the monitoring data of mining-induced earthquake at Fushun Laohutai Mine from 1995 to 2003,a mining-induced earthquake response analysis of a 7-floor brick and concrete structure near Laohutai mining area is made in ADINA,simulating the impact of mining-induced earthquake on structure using ADINA,and the analytic result is shown in the figures with the form of shear diagram,bending moment diagram and displacement of joint time function.The result indicates that the cumulative damage of the structure has the trend to increase in the future years and the structure need reinforcement in time in case it will bring greater loss.It proves that the method may be used to simulate the impact of mining-induced earthquake on structures.It has certain referential value for the future study on forecasting the effect degree of mining-induced earthquake on structure.
