Abstract

The invention discloses a manufacturing method of a lamellar anisotropic rock similar material, and belongs to the technical field of rock surveying. Common cement, river sand, water and other raw materials are casted into a mould so as to form a mold, the lamellar anisotropic rock similar material is manufactured and is then cut into an international-standard cylinder sample, and a triaxial testis carried out. The manufacturing method is simple and fast, the materials are wide in source, low in cost and good in forming effect, and the rock parameters can be adjusted conveniently.

Description

technical field [0001] The invention relates to the technical field of rock surveying, in particular to a method for making similar materials of layered heterogeneous rock masses. Background technique [0002] Rock mass anisotropy refers to the characteristics that the rock's bedding, schistosing, interlayer and directional fracture system make the properties of the rock vary with the direction. There are two types of anisotropy in rocks: one is caused by the existence of micro-cracks and their arrangement and distribution in different directions, that is, layered anisotropy rock mass. This anisotropy will increase with the stress of rock The other is caused by the directional arrangement of rock particles, that is, agglomerate heterogeneous rock mass, and the anisotropy of this rock will not change with the stress of the rock. [0003] At present, the research on rock anisotropy is one of the important topics in the fields of engineering exploration and development, earthq...
