The density,rheological property and stability of the clay cement grout are studied in order to replace the cement grout with clay cement grout,to promote the application of clay cement grout and to control the parameters of the grout to achieve an ideal water control in different conditions.

为了取代单液水泥浆，促进粘土水泥浆的推广应用和控制不同注浆条件下浆液参数达到理想的堵水效果，研究了粘土水泥浆的密度规律、流变性及其影响因素，粘土水泥浆的稳定性、塑性强度测定原理，分析了粘土水泥浆的凝结特性及原理、堵水机理。

The mechanism of underground solidification and induration of cement clay grout is emphatically discussed and tested and vertified in engineering.

简要介绍了高压喷射灌浆新技术的原理，重点论述了水泥粘土浆在地下的固结与硬化机理，并以工程实践作了验证。

The study of clay-cement pastes has revealed that the paste is a pseudo-plastic fluid which has yield value, and that its rheology curve is a curve which does not pass the original point and is concave to the axis of shear strain rate.

在详细研究了粘土－水泥浆的流变特性及其影响因素后认为，该浆液是一带屈服值的假塑流体，其流变曲线为不过原点且凹向剪切速率轴的曲线，流变模型符合改进的双曲模型，该浆液既具有剪切稀释作用又具有振凝性，最后探讨了粘土水泥浆的作用机理。
