基于ANSYS和GeoStudio耦合的充填体底板稳定性分级

摘要

Cracks of different widths and depths are observed in the cemented backfill roof in Wushan Copper Mine resulted from gravity stress and blasting vibration. The stability of backfill is affected when the cracks reach a point. This paper uses ANSYS software and GeoStudio2007 SIGMA/W module to simulate the stress-strain in the roof fissure filling body. The stability classification of filling body's base plate is studied based on ANSYS and GeoStudio coupling. Corresponding suggestions are put forward according to different stability statuses.%武山铜矿胶结充填体顶板在自重应力、爆破振动等作用下产生的不同宽度和深度的裂隙，当裂隙达到一定规模时将影响充填体的稳定性，文中采用ANSYS软件和GeoStudio2007的SIGMA/W模块来模拟含裂隙充填体顶板的应力应变情况，通过2个数值模拟软件的模拟结果的对比验证，研究含裂隙条件下的充填体稳定性，对充填体顶板在不同深度、宽度裂隙影响下的稳定性进行了分级并针对含裂隙顶板的不同稳定性状态提出了合理的支护建议。
