In order to research the influence of the earth fissure’s activity to properties of soil near the earth fissure zone, the existed research conclusions is summarized and some open questions is pointed out. Through soil’s physical and mechanical property tests and scanning electron microscope tests, the variation law of soil’s physical and mechanical properties near the earth fissure and its relationship with soil’s micro-textures characteristics are explained. The results show that earth fissure’s section attribute is variable in different depth and correspondingly the properties and micro-textures of soil near the earth fissure are also changed. Near the surface, the earth fissure is extension fracture; below a certain depth, the micro-textures of earth fissure surface and surrounding soil become more compact, but this influence circle is very limited. Consequently, the physical and mechanical properties of soil also have some changes compared with undisturbed samples, for example, the porosity ratio becomes smaller but the density bigger, and so on. But from macroscopic view, the change of soils’ properties due to earth fissure activity is not very significant which will hardly make influence to engineering project.
