滨海城市填海区复杂地层地铁盾构隧道设计研究

摘要

The complex stratum of the reclamation silt area is characterized by weak consolidation and incomplete settlement.The construction of shield tunnel in this kind of stratum is different from that in other formations in the design.In order to study the design method for shield tunnel under this king of stratum,the paper studies the design of metro shield tunnels in complex stratum of coastal urban reclamation area by contrast analysis with reference to the design of the metro shield tunnels between the station of Liyumen and Qianhaiwan in Shenzhen Bay reclamation area.The general design method for shield tunnel in this stratum is thus obtained and relevant conclusions and suggestions are put forward.%填海淤泥区复杂地层具有软弱且固结沉降未完成的特点,在此类地层建设地铁盾构隧道,设计上有别于其他地层.为研究该地层下盾构隧道的设计方法,结合深圳前海湾填海区鲤鱼门站-前海湾站区间隧道设计情况,采用对比分析的方法,对填海淤泥区复杂地层中地铁盾构隧道的设计进行了分析,得出该地层盾构隧道的一般设计方法,并提出相应的结论和建议.
