摘　　要：宁波轻轨1号线和2号线一期工程之局部盾构隧道区间和车站,发现以沼气为主的浅层天然气。本文依据2号线浅层天然气专项勘察成果,研究了其天然气埋藏分布特征,以及对轻轨建设的影响,提出了防治措施建议。Among the partial shield tunnels and under the subway stations of Lines 1 and 2 of Ningbo urban rail transit project, the shallow natural gas are found, which is mainly composed of methane. Based on the results of The Special Survey on Shallow Natural Gas on Line 2, this paper studied the burial and distribution characteristics of the shallow natural gas, as well as the influence on the rail construction, finally presented the recommendations of the prevention measures.
