Limestone similar material with seepage-chemical-vibration coupling characteristic and preparation method thereof
The invention belongs to the technical field of engineering geologic model tests, and discloses a limestone similar material with seepage-chemical-vibration coupling characteristics and a preparation method, the similar material comprises the following components: aggregate: calcite sand, clay powder and dolomite powder; cementing agents: cement and gypsum; the additives comprise borax, a water reducing agent, nano aluminum oxide and water. According to the invention, a seepage-chemical-vibration coupling similarity theory is provided, similar material aggregate types are determined by considering limestone component information, aggregate grain composition is determined according to limestone mineral grain composition, and the similarity ratio of sample forming pressure to permeability coefficients is determined by considering limestone occurrence ground stress and a sedimentary water environment. The formation environment of limestone is restored to the maximum extent, and the similarity ratio of the vibration frequency and the vibration cycle number is considered. The limestone similar material with the seepage-chemical-vibration coupling characteristic and the preparation method are innovated, and a solid material and theoretical basis is provided for limestone engineering physical model experiments and disaster analysis.
