摘要

依据活塞式驱替注浆渗流的数学模型，推导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关系；依据理论分析，并通过现场试验建立了注浆井底压力和水灰比的经验关系，将结果用于指导灌注桩高压注浆补强工程，取得了良好的实践效果。

Abstract

Based on the mathematical model of high pressure injection cement liquid

a formula of pressure distribution is derived in the district with the cement liquid injection and the raw water area

and the pressure in well bottom to fade away as stop injection cement liquid. The pressure in well bottom relation with the time of the injection and the viscosity of cement liquid

and the permeability in the confined aquifer are analyzed. The empirical formula of the injection pressure with the water-cement ratio is established. The formula can consequently guide the engineering; the good fulfillment results are obtained.
