泥岩地层盾构施工技术——以成都轨道交通30号线一期工程区间盾构施工为例

Shield Tunneling Construction Technology in Mudstone Strata——Taking the Shield Construction of the Phase I Project of Chengdu Metro Line 30 as an Example

近年来,中国城市轨道交通事业的发展表现出惊人的速度,特别突出表现在中国地铁建设的发展。以成都轨道交通30号线一期工程区间盾构工程为依托,结合泥岩地层的特点,通过现场调研、资料分析、数值计算等方法,针对泥岩地区盾构区间施工技术开展研究,并提出泥岩地层盾构施工中常见问题的解决方案,以期为同类项目提供借鉴。

In recent years,the development of urban rail transit in China has shown astonishing speed,particularly in the development of subway construction in China.Based on the shield tunneling project of Chengdu Metro Line 30 Phase I project,combined with the characteristics of mudstone strata,and through on-site research,data analysis,numerical calculation and other methods,conducts research on shield tunneling construction technology in mudstone areas,and proposes solutions to common problems in shield tunneling construction in mudstone strata,in order to provide reference for similar projects.
