Abstract

The invention discloses soft-hard rock composite rock layer similar materials and a method for preparing soft and hard rocks by adopting the similar materials. The hard rock similar material is prepared from, by weight, 80-100 parts of cement, 10-20 parts of kaolin, 8-10 parts of quartz sand, 8-10 parts of iron ore powder, 8-10 parts of blanc fixe and 1-2 parts of rubber powder; the soft rock similar material is prepared from, by weight, 50-70 parts of cement, 30-40 parts of kaolin, 5-8 parts of quartz sand, 5-8 parts of iron ore powder, 5-8 parts of blanc fixe and 2-4 parts of rubber powder.The composite rock layer prepared by adopting the similar materials is large in mechanical strength change range, the mechanical strength can reach 10-50 MPa, mechanical parameters are convenient to adjust, stronger in fragility and stable in mechanical performance, and multiple compound rocks different in mechanical strength can be simulated. The adopted similar materials are wide in source, lowin cost and easy to process.

Description

technical field [0001] The invention discloses a composite rock formation similar material and an application method thereof, in particular to a soft and hard rock composite rock formation similar material and a method for preparing soft and hard rock using the similar material, belonging to the field of rock soil and geomechanical model similar materials. Background technique [0002] In the field of geotechnical engineering and geological engineering, soft-hard rock composite rock formation is a kind of rock-soil mass or geological body that is often encountered, and its physical and mechanical properties bring significant challenges to engineering construction. Because it is difficult to collect real composite rock samples, scholars generally use the preparation of model samples to study the physical and mechanical properties of composite rock formations, and the key to the preparation of model samples is to select appropriate similar materials. The characteristic of comp...
