摘要软流塑地层具有自承载能力低、介质胶结能力差及富水导水的特点，注浆加固处治难度较大。为研究软流塑地层注浆加固参数与物理力学性质之间的关系，选取水泥–水玻璃浆液，采用不同混合体积及注浆压力，开展软流塑地层注浆加固现场试验，围绕地层宏观力学性能，研究注浆加固结石体弹性模量、黏聚力、内摩擦角及渗透系数等参数的变化规律，建立注浆作用对软流塑地层物理力学性能改善的定量关系，通过分析材料配比、注浆压力对地层加固参数的影响规律，揭示注浆加固参数对不同物理力学指标的强化侧重机制，提出注浆加固地层开挖简易判据。研究成果对软流塑地层注浆加固机制的发展完善具有一定的参考意义。

Abstract：Characteristics of soft fluid-plastic stratum include low load-carrying capacity，poor cementing power and rich water，which makes it much difficult to control. In order to study the relation between grouting parameters and physico-mechanical parameters of soft fluid-plastic stratum，field tests of the grouting reinforcement were carried out using cement-silicate grout with different proportions. Based on the formation macro mechanics performance，the quantitative relation of grouting influencing factor and improvement of physical and mechanical properties of the soft fluid-plastic stratum is established via analyzing the change law of elastic modulus，cohesion，internal friction angle and permeability coefficient. Moreover，the criterion on excavation of soft ground has been demonstrated based on grouting reinforcement mechanisms. The results would have certain value for developing the grouting reinforcement mechanism of soft fluid-plastic stratum.
