Abstract:
The origin and distribution character and activity rate of ground fissure in Xi'an is represented. Furthermore, the natural soil sample of Q3 loess and its first buried fossil soil near and within a ground fissure are sampled. The routine soil mechanics test of natural soil sample and the triaxial rheological test of remoulded soil sample are accomplished. The indoor test result shows that the natural density, moisture content, liquid limit and plastic limit become higher near the ground fissure, but the porosity ratio, cohesive force, internal friction angle become lower near the ground fissure, which all is nearly symmetric to the ground fissure. The triaxial rheological test of remoulded soil sample shows that the rheological character of the ground fissure soil is more explicit than that of the loess near the ground fissure. The experimental study shows that the physical and mechanical properties of soil near and within ground fissure are very different. Therefore, the ground fissure is a discontinuous week structural plane in the soil. The laboratory test has valuable reference to the influence analysis study of ground fissure on the engineering structure from the viewpoint of mechanics.
