Similar material for simulating mountain tunnel surrounding rock and preparation method
The invention discloses a preparation method of a similar material for simulating mountain tunnel surrounding rock, which comprises the following steps: selecting and determining raw material components for preparing the similar material and a ratio of the raw material components according to a physical and mechanical parameter range of the similar material for simulating the surrounding rock, mixing the determined raw material components for preparing the similar material in sequence, and pouring into a mold; and after initial setting, standing for 3 hours, demolding, standing and naturally air-drying. The raw material components for preparing the similar material comprise 60-70 parts by weight of gypsum, 4-6 parts by weight of wood chips, 3-5 parts by weight of river sand and 25 parts by weight of water. The method for preparing the similar material is simple and convenient, the preparation cost is low, and the prepared similar material has the advantages of being stable in overall mechanical property and wide in physical and mechanical property parameter adaptability.
本发明公开了一种模拟山岭隧道围岩的相似材料的制备方法，该相似材料通过模拟围岩相似材料的物理力学参数范围选择确定制备相似材料的原料组分及其配比，将确定的制备相似材料的原料组分先后混合后倒入模具，待初凝后静置3小时脱模，静置自然风干得到；所述制备相似材料的原料组分包括60～70重量份石膏、4～6重量份木屑、3～5重量份河砂和25重量份水。本发明制备相似材料的方法简单方便，制备成本低，制备得到的相似材料具有整体力学稳定和物理力学性能参数适应性广的优点。
