Paper Title:
Model Test on Soil Stress and Displacement Changes Induced by Active Ground Fissure
  Abstract

With a large-scale physical model test of active ground fissure, the rules of the soil stress and displacement changes induced by active ground fissure are studied. The results show that, the active ground fissure causes soil stress and displacement field changes within a certain area, namely, soil stress reduce in the hanging wall, but increase in the foot wall. The farther from ground fissure the area is, the smaller the reduction and increase of soil stress caused by ground fissure movement. There are generally 4 soil stress distribution zones induced by active ground fissure, which are, original stress zone of the foot wall, stress increase zone, stress reduction zone and original stress zone of the hanging wall and among which, stress reduction zone is 1.0 to 1.5 times that of stress increase zone. The active ground fissure leads to abrupt displacement phenomena, taking the step shape at its both sides, and as the strata goes from deep to shallow, soil deformation area in section increases obviously. The influence area in the hanging wall is bigger than that in the foot wall.
