Stratum similar material for tunnel temperature field model test and preparation method thereof
The invention discloses a stratum similar material for a tunnel temperature field model test and a preparation method of the stratum similar material. The stratum similar material is prepared from the following raw materials in parts by mass: 5 to 7 parts of graystone, 1 to 3 parts of sand, 3 to 5 parts of soil and 0.5 to 1.5 parts of anti-freezing liquid. Weighing the graystone, the sand and the soil according to the proportion; uniformly mixing the graystone, the sand and the soil mixture; adding the anti-freezing liquid and fully stirring; the mixed materials are put into a 130 * 10 mm round forming die, and tamping forming is conducted; and putting the molded mold into a curing box, curing for 24 hours, and demolding to obtain the surrounding rock similar material for the tunnel temperature field model test. The same heat transfer rule of similar materials and actual surrounding rocks can be achieved, the heat conductivity coefficient of the similar materials can be changed by changing the material proportion so as to adapt to thermodynamic properties of different tunnel surrounding rocks, and possibility is provided for simulating the time-space evolution rule of a real cold region tunnel temperature field.
本申请公开了一种隧道温度场模型试验地层相似材料及其制备方法，原料按质量份数配比为：玄武石5~7份，砂1~3份，土3~5份，抗冻液0.5~1.5份。按照比例称取玄武石、砂和土；将玄武石、砂和土混合物混合均匀；加入抗冻液并充分搅拌；将混合好的材料放入130*10mm圆形成形模具中，夯实成型；将成型后的模具放入养护箱中养护24 h后脱膜，即可得用于隧道温度场模型试验的围岩相似材料。能够实现相似材料与实际围岩相同的传热规律，并能通过改变材料比例改变相似材料的导热系数，以适应于不同隧道围岩的热力学性质，为模拟真实寒区隧道温度场时空演化规律提供了可能。
