Pebble surrounding rock similar material with seepage stress erosion coupling characteristic as well as preparation method and application of pebble surrounding rock similar material
The invention belongs to the technical field of tunnel and underground engineering model tests, and discloses a pebble surrounding rock similar material with seepage stress erosion coupling characteristics and a preparation method and application of the pebble surrounding rock similar material. The main materials comprise a coarse aggregate, a fine aggregate and a filling material, and the conditioning agent comprises silicone oil, glycerol, liquid paraffin and vaseline; the main material adopts quartz sand, in the main material, the sum of the mass of the coarse aggregate and the mass of the fine aggregate accounts for 20-80% of the total mass of the main material in percentage by mass, the mass ratio of the coarse aggregate to the fine aggregate is (0.25: 1)-(4: 1), and the balance is the filling material; in percentage by mass, the weighting agent accounts for 4-20% of the mass of the main material, the cementing agent accounts for 2-10% of the mass of the main material, the mixing water accounts for 8-12% of the mass of the main material, the silicone oil accounts for 0-8% of the mass of the main material, the glycerin accounts for 0-8% of the total mass of the main material, the liquid paraffin accounts for 0-8% of the mass of the main material, and the vaseline accounts for 0-8% of the mass of the main material. The pebble surrounding rock similar material is high in similar simulation degree, moderate in parameter change range, convenient to prepare, low in cost and capable of meeting the seepage stress erosion coupling characteristic.
