摘要

动水环境中的注浆扩散规律对指导突涌水治理注浆设计与施工具有重要意义。通过开展水泥-水玻璃（C-S）浆液单一平板裂隙动水注浆模型试验，揭示了基于试验条件下的C-S浆液裂隙动水注浆扩散过程的非对称椭圆（AE）扩散规律，提出浆水速比的概念并用其拟合AE扩散控制参数随时间的变化曲线，分析了浆水速比对浆液扩散范围的影响，最终建立了描述浆液扩散迹线的瞬态方程。研究结果表明：浆液扩散迹线可以采用随时间变化的非对称椭圆进行描述；逆水扩散距离和扩散开度与浆水速比正相关而浆液顺水扩散距离与浆水速比负相关。并据此对裂隙动水注浆设计提出了建议，希望对实际注浆工程提供一定借鉴。

Abstract

Diffusion law of dynamic grouting has directive significance to the grouting design and construction. Simulation tests of crack dynamic grouting with cement-silicate (C-S) slurry are carried out. The asymmetric ellipse (AE) law is revealed to describe the C-S slurry diffusion process under laboratory conditions. The concept of “speed ratio of slurry to water” is proposed to fit the AE parameters-time curve. How the speed ratio of slurry to water affects grouting diffusion range is analyzed. The transient equations describing slurry diffusion trace is established. The results show that: the slurry diffusion trace could be described with asymmetric ellipse which varies with time. The speed ratio of slurry to water is positively correlated with diffusion distance against flow direction and lateral diffusion distance. The speed ratio is negative correlated with diffusion distance along flow direction. Based on the results above

suggestions for grouting design are proposed.
