摘要
以深圳地铁太安站—怡景站区间重叠交叉双层隧道为研究对象,对复杂环境下的关键施工技术进行阐述与分析,利用ABAQUS建立有限元计算模型,对施工过程进行数值模拟计算,并与现场的实际监测资料进行对比分析,最终证明在城市地质条件较差的情况下,群洞重叠隧道借助超前小导管注浆加固的辅助施工方法,可实现上下重叠隧道错开一定开挖步距后同步进行开挖。
Based on overlapping tunnel from Tai＇an Station to Yijing Station of Shenzhen metro, the authors describe and analyze the key construction technology in complex environment. They set up finite element model by ABAQUS to analyze the construction process and compare with monitoring data. The results show that excavating synchronously after staggering some distance between the overlapping tunnels can be realized by pre-grouting with small pipe in poor geological condition.
