• In order to investigate the mechanism of hydraulic fracturing in soils, several laboratory tests are performed on compacted hollow cylindrical specimens of a cohesive soil under different confining pressures. The results indicate that hydraulic fracturing in soil initiates when total stress near the borehole reaches to the failure condition of the soil in unconsolidated undrained state. Based on Mohr-Coulomb failure criteria, theoretical solution of hydraulic fracturing pressure is derived and physical meanings of empirical equations appeared in previous papers are discussed. Then the general expression of hydraulic fracturing in pore pressure existance is obtained.
