摘要：

针对煤层开采后上覆含水砂岩地层疏干排水导致的地层不均匀沉降对斜井管片结构的影响，采用了相似模型试验手段对斜井穿越粗粒砂岩与砂质泥岩交界区域进行相似模拟试验，通过模型试验模拟不同的地层压力、孔隙压力和排水速率条件下的含水地层沉降变化规律及斜井管片纵向和环向应力应变分布情况，分析得出了斜井管片结构附加应力的分布规律以及影响因素，同时根据模型试验提出了含水地层不均匀沉降引起的管片附加应力和地层围岩压力、孔隙水压力作用对斜井管片结构的影响。

Abstract:

To study the influence of uneven settlement on the structure of inclined shaft segment caused by the drainage of overlying water?bearing sandstone after coal mining, a similar simulation test was carried out on the area where inclined shaft crossed the boundary between coarse?grained sandstone and sandy mudstone. The settlement rule of water?bearing sandstone and longitudinal and hoop stress?strain distribution of inclined shaft segment was simulated by model test in different formation pressure, pore pressure and drainage rate. The distribution rule and influencing factors of additional stress in the inclined shaft segment were analysed. At the same time, according to the model test, the influence of additional stress, surrounding rock pressure and pore?water pressure caused by uneven settlement on the inclined shaft segment was put forward.

Key words: civil engineering, tunnelling engineering, model test, uneven settlement, additional stress
