【摘要】 采空区在动载作用下会发生严重的地表变形,引起土体塌陷、建筑物失稳、地下管线破坏等灾害性事故。采空区在动荷载下的变形研究是合理开发和利用采空区的重要保证,本文综述当前采空区在动力荷载影响下的地表变形的国内外研究现状,重点介绍诱发采空区的变形的动荷载的类型、变形分析方法、变形治理方法等内容。在对现有成果分析的基础上,指出采空区变形研究存在的问题和发展的方向,为今后的研究提供参考。更多还原

【Abstract】 Mined-out region under dynamic loads will produce a severe deformation,causing the disasters of soil subsidence,building instability and underground pipeline damage. So the research of deformation under dynamic loading has become the important guarantee for rational development and utilization of mined-out region. The current research state of problems associated with mined-out regions is reviewed systematically,including the dynamic load types,deformation analysis method,deformation control method. Some problems needed to solve and development direction in future are also pointed out.更多还原
