Soil fracture grouting strain parameters
WebFracture grouting has been widely applied in geotechnical engineering in order to enhance bearing capacity and reduce permeability of soils. However, the fracture propagation of … WebThe arching in soils of the cases with CAR (cavity aspect ratio) of 1.2 is generally more noticeable than that of the cases when CAR is 1/3 and 3. Besides, when the spacing between grouting bulbs is 1.0 m and the CAR is identical, soil arching decreases almost linearly as the horizontal dimension of the elliptical bulb increases.
