Weakly cemented soft rock-like hollow cylinder sample material and preparation method thereof
The invention discloses a weakly cemented soft rock-like hollow cylinder sample material and a preparation method thereof, and belongs to the technical field of mine and underground engineering safety. Aeolian sand is used as a framework material, bentonite is used as a filling cementing material, calcined gypsum powder and talcum powder are used as adjusting materials, water is added, the materials are mixed according to the mass ratio of 1: 0.66: 0.44: 0.28: 0.36, and the weakly cemented soft rock similar material is obtained. The weakly cemented soft rock-like material prepared by using the raw materials, the raw material ratio and the preparation method has the characteristics of physical similarity and mechanical similarity with the original weakly cemented soft rock, and can be used for testing and theoretical analysis of the weakly cemented soft rock under a complex stress path.
本发明公开了一种类弱胶结软岩空心圆柱试样材料及其制备方法，属于矿山与地下工程安全技技术领域。以风积砂作为骨架材料，以膨润土作为填充胶结材料，以熟石膏粉和滑石粉作为调节材料，加上水，按照质量比1∶0.66∶0.44∶0.28∶0.36的比例混合，得到类弱胶结软岩材料。利用本发明原料、原料配比以及制备方法制备的类弱胶结软岩材料与原状弱胶结软岩具有物理相似和力学相似特点，可用于复杂应力路径下弱胶结软岩的试验及理论分析。
