Results show that gas release in gassy sand will cause the additive deformation of tunnel and additive stress of the shield segment, and make important impacts on the global displacement of tunnel but little influences on the stress of shield segments and the relative displacement of tunnel. It is inclined to arouse the differential settlement and cracks on the tunnel so as to cause hazardousness. Re-accumulating of the gas can also produce additional stress and the additive resilience, but it can be ignored in practical engineering because the influence degree is small. The shallow gas in reservoirs is appropriate to be discharged before construction of the subway tunnel.

研究结果表明：气体释放将引起隧道产生附加变形和管片附加应力，浅层气体释放对地铁隧道结构应力和结构相对变形影响较小，而对隧道整体位移影响较大，易引起不均匀沉降，导致隧道裂缝或断裂，进而引发危险；气体重新回聚时，隧道产生的附加应力和回弹位移量较小，工程中可不予考虑；地铁隧道施工前，宜对浅层气体进行预先排放。
