| 摘 要： | 以淮南某矿区为例,用有限元分析了厚表土层下煤矿开采引起的地表沉陷、地表倾斜、水平移动及孔隙水压的变化规律,总结了地表移动的基本特征和相关参数;同时分析了位于该矿首采区的铁路桥因地表变形产生的附加内力的变化,为采动区的建筑物保护提供了科学依据。

| Abstract: | With the example of one coal mine in Huainan,a simulation analysis by finite element on ground movement due to coal exploitation is carried out.Through simulation analysis,the laws of variation for ground subsidence,ground inclination,plane movement regulation and pore pressure are given.The basic features and the related parameters of ground movement are obtained.Additional internal forces of a railway bridge over mining subsidence area is analyzed too,the results are of referential value for building protection in mining area. |
