Surrounding rock material and proportioning method thereof
The invention discloses a surrounding rock material and a proportioning method thereof, the surrounding rock material comprises an aggregate and a cementing material, the aggregate is fine sand, and the cementing material is cement and gypsum; the proportioning method is as follows: the water content ratio of the fine sand to the cement to the gypsum is (7.5-9.5): (0.5-1.5): (0.3-0.7): (22-28); according to the surrounding rock material, only the four raw materials including the fine sand, the cement, the gypsum and the water are adopted, the number of the materials is small, the materials are easy to obtain, cost is low, and the surrounding rock material is non-toxic and harmless and is green and environmentally friendly compared with similar materials adopting the raw materials including engine oil, barite powder and the like, and the cost can be controlled in a large-scale model test; iV-grade and V-grade surrounding rock similar materials for most river-crossing bridge model tests can be simulated; and the similar material is simple in preparation method, convenient to cast and form, easy in operation flow and stable in material property.
本发明公开了一种围岩材料及其配比方法，包括骨料和胶结材料，所述骨料为细沙，所述胶结材料为水泥和石膏；所述配比方法如下：细沙：水泥：石膏：含水率为(7.5‑9.5)：(0.5‑1.5)：(0.3‑0.7)：(22‑28)；本发明仅采用了细沙、水泥、石膏及水四种原材料，材料种类数量较少、取材容易、成本较低、无毒无害，相对于采用机油、重晶石粉等原料的相似材料，绿色环保且在大比例模型试验中能控制成本，本发明提出的围岩材料，可模拟大部分跨河桥梁模型试验的Ⅳ、Ⅴ级围岩相似材料；且相似材料的制备方法简单，浇筑成型方便，操作流程容易，材料性质稳定。
