摘要
朱仙庄煤矿皮带走廊建于20世纪80年代。由于“五含”疏水对地下水位的影响,皮带走廊可能会发生不均匀沉降,使得建筑物内力发生变化,在结构中产生应力集中,从而导致建筑物变形破坏,严重影响煤矿运输安全。选取皮带走廊中间一段为研究对象,采用ANSYS数值模拟软件,模拟分析4种不同沉降工况下的皮带走廊位移和内力变化规律,并分析研究了不同工况对建筑物静力力学性能的影响,可为皮带走廊应对地基不均匀沉降提供参考。
The belt corridor of Zhuxianzhuang Coal Mine was built in the 1980s.Due to the impact of the“Five Aquifers”drainage on the groundwater level,the uneven settlement will be occurred,causing changes of the internal force and stress concentration in the structure,resulting in deformation and damage of the building and seriously affecting the safety of coal transportation.In this paper,the middle section of the belt corridor is selected as the research object,and Ansys numerical simulation software is used to analyze the displacement and internal force changes of the belt corridor under four different settlement conditions.The influence of different working conditions on the static mechanical properties of the building is analyzed,which can provide a reference for the belt corridor to deal with the uneven settlement of the foundation.
