| 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,本文利用有限元软件ABAQUS进行受力机理模拟分析,得到冻结管应力、位移分布规律,从而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,并提出相关施工建议为后期矿井建设提供参考。 |
| 英文摘要: |
| in the light of freezing pipe,sSfracture of Yangcun coal mine auxiliary shaft in 407.3m ∽ 445.35m section of thick sandy layer,this paper used the finite element software ABAQUS to simulate analysisclay to get the freezing pipe,s stress and displacement ,thus detecting that the position of the fracture of freezing pipe was in zhe junction of the sandy clay and the sand, by comparing with the monitoring results, analysed that the main reason of freezing pipe,s rupture was the two different kings of soil frost heave, and provided relevant suggestions to the next construction. |
