Theoretical Derivation of the Column (Ball) Expansion in Pressure Grouting

Abstract:

Based on the assumptions:(1)The grouted soil is homogeneous and isotropic;(2)Slurry is Newtonian;(3)Slurry be injected into the strata from the bottom of grouting pipe;(4)In the soil slurry was spread in the ball shape, theoretical formula of the column (ball) expansion of the pressure grouting is derived , and described the FH3’s curing mechanism. This research could provide theoretical guidance for the implementation of grouting.
