| 摘 要： | 针对煤矿立井井筒深厚表土层的支护，提出了采用双层钢板高强混凝土复合井壁结构。通过模型试验，得到了这种井壁结构的应力特性和强度特征，通过理论分析和试验结果给出了双层钢板高强混凝土复合井壁承载力的计算公式，从而，为该种井壁结构的实际应用提供了设计依据。其研究成果已在4个井筒中得到了成功地应用。

| Abstract: | Aiming at the deep alluvium support of coal shaft, the composite shaft lining of high strength concrete and double steel cylinders is presented. Through model experiments, the characteristics of stress and bearing capacity of the composite shaft lining of high strength concrete and double steel cylinders are obtained. In the end, an equation for calculating the ultimate bearing capacity is given based on the theoretical research and experimental results. Thus, the studied results may provide a design basis for engineering practice of this kind of shaft lining structure. The studied results have been successfully applied in four shafts. |
