摘要
针对上海地铁唐镇东站-华夏东路站区间盾构穿越沼气地层，提出并实施了地面钻孔释放、沼气浓度监测、隧道通风、优选盾构施工参数等综合措施，实践证明措施可行并取得了较好效果。
Based on the example of Shanghhai subway shield tunneling in marsh gas stratum between Tang Town East Station and East Huaxia Road Station, this paper proposes and implements comprehensive measures, including marsh gas release by drilling holes on the ground, concentration monitoring, tunnel ventilation, shield construction parameters optimization, which have been proved viable and achieved good results.
