摘要
通过大量试验证明水泥基浆液的粘度存在时变性,其规律符合指数函数分布;而动切力随时间变化不大,可视为无时变性。在此基础上,建立了用于岩体裂隙的稳定性浆液注浆扩散模型,开发了计算机程序。通过2个工程实例的对比结果证明了这一理论的计算结果符合工程实际。
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.
