摘要
本文在依相似理论建立的竖井模拟试验台上,对位于特殊地层中的立井井壁受力问题进行了模拟研究,首次证实了粘土层对井壁作用有纵向附加力,并得到了该力的数值、分布及变化规律。得出附加力是导致矿井井壁结构破坏的重要因素的结论,指出位于特殊地层的立井井壁结构设计应当采用三维空间理论进行计算。
This paper presents a simulation investigation about bearing capacity of vertical shaft lining surrounded by strara with special structure. A vertical shaft model established on the test rig is designed in accordance with the principle of the similarity theory .The study confirms that there is an additional vertical force acting on the shaft lining caused by surrounding clay. The values, distribution, and the way of variation of this force are calculated. The authors show that this force is an important factor which causes the destruction of the shaft lining, and also indicate that the structure of the shaft lining should be designed by adopting 3-D elastic theory.
