| Abstract: | In this paper, the types, materials and methods of stabilizing grout in Shanghai district and other soft - clay areas during excavation of foundation pits are discussed, the procedure , depth and width of stabilizing grout for soil in the passive areas are studied. Through two practical examples, the effects of stabilizing grout are analyzed in arccordance with the improvement of the soil properties, the displacement of the undergrond continuous concrete wall, the settlement of the surrounding soil and the change of standard penetration. The above - mentioned results may have guide significance for engineering practice. |
