| Abstract：Mud is used to stabilize the borehole wall, and suspend and remove drilling residuals, of which the rheological behavior and hydraulic parameters are very important. This work carried out an experimental study on the rheological behavior of bored-pile mud. Formulas of rheological parameters were deduced. Borehole-wall stabilization, drilling residual removal and suspension characters of bored-pile mud were analyzed. The results have theoretical and practical significance for evaluating and optimizing bored-pile mud. |
