地下水位下降对矿区附近红粘土地区房屋开裂的影响

The Influence of Groundwater Line Lowing to the Building Cracking in the Red Clay Region

在矿山地质灾害鉴定中,一般采用工程力学原理,计算并确定矿山顶板的安全厚度、开采移动盆地的影响范围。而在有些地区出现的矿山地质灾害中,单纯地用岩土工程力学原理则无法解释,必须结合矿山开采过程中水文地质条件的变化特征方能作出科学的鉴定。本文通过红粘土地区房屋开裂成因的剖析,说明矿山地下水位下降是导致房屋开裂的重要影响因素。

In the diagnosis of mining geologic disaster, it usually use the engineering mechanical principle to calculate and ensure the safe thickness of mining But in the geologic disaster of some regions, it can＇ hanger, the influenced scale of explore the moving basin t explain only with geotechnical engineering mechanics. It can make scientific diagnosis only by combine the hydrogeologic condition when exploring the mining. In this paper, by analysis the reason of building cracking in the red clay regions, it points out that the mining groundwater line is an important reason which causes the building cracking.
