开采沉陷在土体中传递的实验研究

The experimental study on the transmit of the mining subsidence in soil

为了探索开采沉陷在土体中的传递规律,设计了相似材料模型实验系统.实验结果表明,开采沉陷边界在土体中的传递与土层的性质是密切相关的;地表下沉由采动引起的基岩面下沉、地下水位下降引起的下沉、附加荷载引起的下沉和土体的流动组成.实验结果可以解释目前所出现的厚表土层地区的特殊沉陷规律.

In order to exploring the rule of the transmit of the mining subsidence in soil, it specially designs the experimental system of the similar model, the results show that the transmit of the mining subsidence on the edge of the soil is firmly related to the property of every soil layer; the surface subsidence consists of the subsidence of the original rock, the subsidence caused by the descend of the underground waterlevel, the subsidence caused by the additional load and the fluxion of the soil. The experimental results can explain the special rules of the mining subsidence which occurred in the soil.
