| 中文摘要: |
| 针对杨村煤矿副井407.3m～445.35m段特厚砂质粘土层冻结管断裂情况，利用有限元软件ABAQUS进行受力机理模拟分析，得到冻结管应力、位移分布规律，判断出冻结管断裂位置在砂质粘土与砂土交界处，通过与现场监测情况进行对比，分析出冻结管受力断裂主要原因在于两种土层冻胀不同造成的，为后期矿井建设提供参考。 |
| 英文摘要: |
| With regard to the fracture of freezing pipe in the thick sandy layer of Yangcun coal mine auxiliary shaft in 407.3m ～ 445.35m, finite element software ABAQUS was operated to conduct a simulation analysis of clay to get the stress of freezing pipe and the displacement, thus detecting that the position of the fracture was in the junction of sandy clay and sand. By comparing with the monitoring results, it can be concluded that two different kinds of soil frost heave was the main reason for the rupture. Suggestions are provided as reference for future mine construction. |
