| Abstract: | Based on the in-situ pressure-grouting experiments and the high strain dynamic tests of hand-formed pile built on the fracture zone, the process, parameters and effect of pressure grouting are introduced in this paper. The mechanism of increasing the ultimate bearing capacity of the piles by grouting is analyzed. |
