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...
