Abstract

Abstract

According to the intensity peculiarity of soil body and the assumption that the destroyed bodies by abrupt gush are cuboids or cylinders, the writer deduced a calculation formula of stability of the abrupt gush of soil and water concerned about the above. And the calculation result manifests that, for generic cohesive soil, the partial safety factor of resistance, taken intensity into account, are over three times of those not done. No abrupt gush phenomena have come about in digging of building foundation pits in Hankou district, which demonstrates that the intensity of resistive shearing has a not to be neglectable effect on resistance. So the stability analyses of abrupt gush concerned about intensity of the soil body are relatively close to engineering reality.
- building foundation pit,
- abrupt gush of soil and water,
- strength of soil body,
- partial safety factor of resistance
