试验结果表明，水泥基浆液的黏度随时间变化，且黏度随时间变化服从指数函数规律，其中剪切无明显规律；E，某水泥基浆液在t时刻的剪切力τ0(t)接近于其初始值τ0(0)。基于注浆的时效特性，提出了适用于岩体裂隙的注浆扩展模型，并用vc++语言编写了注浆扩展预测程序。该扩散模型在两个工程中的应用取得了成功。
Experimental results indicate that the viscosity of cement-based grouts is time-dependent,and the law conforms to an exponential function where the shear shows no apparent law,i. e.,τ0 (t ) ,the shear of certain cement-based grout at time t,is nearly equal to its initial value τ0( 0) . Based on time-dependent behavior of grouts,a grouting spreading model suitable for rock mass fissures is presented and a programme to predict the grouts spreading with VC++ language is developed. The application of the spreading model in two projects has proved to be successful in practice.
