Resist Liquefaction of Subsoil of Metro and Improvement of Segments of Shield Tunneling
Nanjing’s metro is studied as a example to introduce resist liquefaction method in this paper. Dynamic diffuse theory of structure is supposed to evaluate the width and depth of foundation treatment to resist the seismic liquefaction to think of metro structure, liquefied soil layers and different liquefaction-index. High pressure jet grouting method is researched as shield machine construction through foundations of buildings or ancient wall. An improved segments of shield tunneling method is suggest to ensure the resist liquefaction method to success.
