This study collects 198 sets of field measurement data due to shield tunneling cases reported in different parts of the world from 1980 to 2008. A hyperbolic model is proposed to simulate the surface settlement-time relationship due to shield tunneling constructed in different types of soils with different shields.

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.

研究結果表明：氣體釋放將引起隧道產生附加變形和管片附加應力，淺層氣體釋放對地鐵隧道結構應力和結構相對變形影響較小爽爽的电影AV片，而對隧道整體位移影響較大91人妻PORNY九色最新社区，易引起不均勻沉降，導致隧道裂縫或斷裂水蜜桃在线无码视频免费，進而引發(fā)危險丝袜剧情国产AV办公室；氣體重新回聚時，隧道產生的附加應力和回彈位移量較小WWW尤物在线，工程中可不予考慮91插插插插；地鐵隧道施工前，宜對淺層氣體進行預先排放国产精品永久久。
