地表移动带范围内建构筑物安全可靠性分析

地表建构筑物位于在生产矿山地表开采移动范围内，如果按照一般圈定地表移动范围原则判断建构筑物的安全可靠性，结果是不安全或者预留保安矿柱可保证安全。为分析地表移动带范围内建构筑物安全可靠性，采用FLAC3D软件建立数值模拟模型，对矿区地表移动进行分析研究，并结合建构筑物的破坏等级评判标准，可以更加合理地判断地表移动范围内建构筑物的安全可靠性，对存在相似条件的矿山具有一定的借鉴意义。

Safety and Reliability Analysis of Buildings in the Range of Surface Movement Zone

Surface buildings and structures located within surface mining movement in producing mines.If the safety and reliability of buildings and structures are judged according to general principle of delineating the range of surface movement,the result is unsafe or security pillars are reserved to ensure safety.To analyze the safety and reliability of buildings in the range of surface movement zone,using FLAC3D establish numerical simulation model and study the surface movement of mining area,also combining with the damage grade evaluation criteria of building,the results could be reasonable,which has a certain reference for similar conditions mines.
