| 摘 要： | 建立了高压注浆渗流的数学模型,推求出高压注浆过程中浆体区和原水体区的压力分布,以及停止注浆后井底压力的消退情况。分析了注浆井底压力和原区压力与注浆时间、浆液粘度、渗透率、计算点与注浆井距离等的关系;通过现场试验建立了注浆井底压力和水灰比的经验关系,并将结果用于指导灌注桩高压注浆补强工程。 |
| 关 键 词： | 高压注浆 钻孔灌注桩 渗流模型 注浆压力 水灰比 工程应用 |

| Abstract: | Based on the mathematic model of the high pressure injection of cement liquid,the formula of pressure distribution was presented in the district with the cement liquid injection and the raw water area,and the pressure in well bottom to fade away when stopping injection cement liquid.The correlation between the pressure in well bottom and the time of the injection,the viscosity of cement liquid,the permeability in the confined aquifer.The empirical formula of the injection pressure with ratio of water to cement was established.Application of the formula consequently guided the engineering,and obtained good fulfillment result. |
| Keywords: | high pressure injection cast-in-situ pile seepage model injection pressure ratio of water of cemen engineering application |
