矿山沉陷区新建建筑物可行性分析

论文就矿山沉陷区开采煤层上覆岩层变形规律、沉陷区形成基本特征及稳定性进行了分析,对竖向集中荷载与矩形截面竖向均布荷载作用下的建筑物荷载传播深度进行分析。通过对建造建筑物时间的选择、地基附加应力传播深度的确定,评价地表残余移动变形对地基的影响。对矿山沉陷区能否新建建筑物进行可行性分析,为地基附加应力传播范围提出分析方法,为沉陷区新建建筑物提供理论依据。论文对一工程实例进行了可行性论证分析,证明了理论的可行性并得出了重要的结论。

Feasibility analysis of new building construction in the subsisdence area by underground mining

This article analyses the deforming regulation of rock strata on the coal goal, the basic characteristics and stability of subsidence area and also analyses the translation depth of the building load, which is under the function of both the vertical load and the square section even vertical load. Thus we carry out the feasibility analysis whether translation the new building can be built or not through selecting the starting time, dertermining the travelling depth of the additional foundation stress and evaluting the effect of the additional strain of the foundation . At last we propose the analyzing method of translation range of the the additional of foudation stress and give the theoritical according to constructing new buildings. And also we carry out the feasibility analysis on a practical project, prove the feasibility and get a significant conclution.
