摘要:
以成都轨道交通 6 号线三期工程为依托，针对泥岩、砂岩及高瓦斯地层，综合考虑安全性、经济性、适用性等因素，对盾构法、矿山法及明挖法等3种施工方法进行了对比分析，对试验段的不同开挖方案进行了探讨。结果表明：采用矿山法和明挖法相结合的方式分段施工地铁高瓦斯区间隧道，能够有效降低施工风险；相比于钻爆法，悬臂掘进机开挖法在施工工效、施工质量及施工安全方面具有显著优势，但施工造价相对较高。
Abstracts:
Based on the third\|phase project of Chengdu Metro Line 6, targeting mudstone stratum, sandstone stratum and high gas stratum, comprehensively considering factors including safety, economy and applicability, three construction methods of shield tunneling, mining and open excavation are comparatively analyzed, and different excavation schemes are discussed taking test section as object. Results show that applying combination of mining method and open excavation method to the construction of metro high gas tunnel section by section can effectively reduce construction risks. Compared to drilling and blasting method, boom\|type roadheader method has significant advantages in construction efficiency, quality and safety, but the construction cost is relatively high.
