Design of grouting parameters in rock based on grouting time

  • 摘要: 水泥灌浆常被用来提高岩体的完整性和降低其渗透性,其工艺参数的设计目前主要依赖于灌浆工程师的经验和类似工程的类比,灌浆时间一般不包括在灌浆设计参数中。根据水泥浆液在光滑顺直裂隙中的扩散运动方程,考虑水泥浆液的宾汉体流变性质和其颗粒特性,并在给出灌浆特征时间概念的基础上推导出灌浆过程中浆液扩散比与灌浆时间比的关系,提出了基于灌浆时间的灌浆结束标准,并结合岩体裂隙开度分布规律对其在灌浆设计和施工中的运用进行了分析,可为灌浆工程的设计和施工提供有益的参考。
    Abstract: Cement grouting is used to improve the integrity and to reduce the permeability of rock mass. The design of grouting parameters depends mainly on the engineer's experience and engineering analogy, and the grouting time is generally not included in the design parameters. Based on the diffusing equation for cement grouting in a smooth and straight fracture, the relationship between that of penetration length and the ratio of grouting time is derived considering the Bingham rheological properties of cement grouting and the properties of cement particles. The grouting criterion based on the grouting time is proposed and analyzed in the grouting design and construction considering the distribution of rock fracture aperture. It may provide a reference for the grouting design and construction in similar projects.
