摘要
结合温州市域铁路S2线瓯江北口隧道详勘中沼气喷发现象,研究温州软土地层中沼气的分布形式及集聚情况,通过先行试验段沼气释放,采用控制释放措施,在试验段施工过程中验证有控释放的效果、摸清沼气的分布及集聚情况并对其结果进行分析,验证了控制释放的可行性及必要性,为后期沼气释放及隧道盾构推进提供经验依据。
Through detailed survey of the Oujiang Beikou Tunnel on the S2 Line of Wenzhou City Railway,biogas spraying phenomenon was discovered to study distribution and accumulation of biogas in soft soil layer in Wenzhou.The controlled release measures are adopted to verify effect of controlled release during construction of the test section,find out distribution and agglomeration of biogas,analyze the results,test feasibility and necessity of controlled release,and provide empirical basis for later release of biogas and tunnel shielding.
