为了更深入的研究穿越江河的隧道工程软土地基处理,结合上海地区近些年来大量穿越黄浦江和长江的隧道旁通道设计和施工的工程实践,介绍了埋深、开挖断面大、含水丰富的粘土地层水平冻结加固设计技术.通过有限元分析和工程实践,越江隧道旁通道加固采用通道两边对打水平双排冻结孔冻结,冻结壁厚度和强度能够满足设计要求.对沿江沿海地区隧道工程的设计和施工具有一定的指导作用.
In order to further study the soft soil foundation treatment of the tunneling projects crossing the river and combining with the engineering practice of design and construction of tunnels in the tunnels that pass through the Huangpu River and the Yangtze River in large quantities in Shanghai in recent years, Of the clay stratum horizontal freezing reinforcement design technology.Finally, through the finite element analysis and engineering practice, the cross-river tunnel reinforcement by the channel on both sides of the horizontal double-frozen hole frozen, frozen wall thickness and strength to meet the design requirements of the coastal area along the Yangtze River Tunnel Engineering The design and construction of a certain guiding role.
