Abstract
A theoretical model is proposed to estimate the flow patterns of grout suspensions during grouting process with the influence of flowing groundwater. A comprehensive analysis is conducted on the proposed model and the laboratory test results of previous studies. It is concluded that: the temporal and spatial variation of grouting penetration can be analyzed with ideal fluid hypothesis, while the information of grouting pressure can be acquired through real-time monitoring. Thus, the whole information during grouting process is acquired. The pressure of grout in upstream direction is larger than in downstream direction, and the danger of ground uplift is higher. Combining the uplift mechanism of overlying rock mass and grouting penetration and pressure distribution rule, the allowable injection pressure and the risk for overlying rock mass uplift can be estimated. The proposed model provides theoretical basis for risk assignment for overlying rock mass uplift during grouting process.
