| 摘 要： | 根据高压注浆渗流的数学模型，推求出注浆体区和原水体区的压力分布公式，以及停止注浆后井底压力消退情况。分析了注浆井底压力与注浆时间、注浆液粘度的关系以及与渗透率的关系；建立了注浆井底压力和水灰比的经验关系，对灌注桩高压注浆补强工程具有良好的指导意义。 |
| 关 键 词： | 高压注浆法 注浆压力 水灰比 数学模型 |

| Abstract: | Based on the mathematical model of the seepage in jet grouting,the paper inferred the pressure distributed formula in the district with the cement liquid injection and the raw water area, and the decline pressure in well bottom after stopping injection cement liquid. The pressure in well bottom relation with grouting time, the viscosity of cement liquid and the permeability in the confined aquifer were analyzed. The empirical formula of the grouting pressure with ratio of the water cement was established. The results are used in the engineering, and a good fulfilment is obtained. |
| Keywords: | jet grouting grouting pressure ratio of water to cement mathematical model |
