摘要
在工程实践的基础上，对上海等软土地区基坑工程中注浆加固的类型、材料、工法进行了探讨；着重对坑底被动区土体注浆加固的形式、深度、宽度进行了研究；引入了两个实例，从土体注浆加固后土性各项指标的改善和土体注浆加固后地下连续墙体位移量、周围土体沉降、标准贯入度等的变化分析了注浆加固效果；本文的结果对工程实践有一定的参考价值。
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.
