Model test on soil stress and displacement changes induced by active ground fissure
Through 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 reduce in the hanging wall, but increase in the foot wall of ground fissure, and from the foot wall to the hanging wall, there are 4 soil stress distribution zones induced by active ground fissure, i.e., 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~ 1.5 times that of stress in- crease zone. Meanwhile, the active ground fissure leads to abrupt displacement phenomena, taking the step shape at its both sides, and the influence area in the hanging wall is bigger than that in the foot wall.
