Abstract:According to the engineering geology of the section with super shallow cover in Nanjing Yangtze River Tunnel,the risks of shield tunneling were analyzed.Based on the calculation of slurry pressure and slurry param-eters,a rigorous construction scheme has been drawn up to strengthen the information-oriented management dur-ing the construction and to ensure the safty of rapidly under-passing the section with super shallow cover.The technique successfully adopted herein not only has accumulated valuable experi...
Keywords:Slurry shield  Super shallow cover  Slurry pressure  Slurry parameter  Segment floating
