摘要
In order to analyze the diffusion mechanism of single grouting in fault, a large sized test device was developed to conduct simulated grouting diffusion test in fault medium by single injection pipe. At the same time, the real-time key parameters including injection pressure, injection rate, soil stress, seepage stress, and effective stress were acquired. In addition, the fault medium was excavated by nine sections, and the three-dimensional diffusion form of slurry was therefore sketched. It can be concluded that the soil stress, seepage stress and effective stress increase continuously during grouting while decrease gradually when grouting is stopped. The volume of injected cement and waterglass slurry is 7.3% of the volume of fault medium. The the consolidation body of grout with the maximum thickness of 133 mm is in the section of the -50 mm. Based on test conclusions, four suggestions are proposed for the design and application of grouting engineering.
