| 中文摘要: |
| 为了解决岩石工程相似模型实验中传统相似材料难以模拟深部软岩低强度、大变形和强流变的问题,本文选用70#沥青（产量大、成本低、粘弹性、易成型、易软化等）和海砂作为深部软岩的相似模拟材料。采用连续加压法对其进行了单轴压缩实验,对不同配比下试件的密度、抗压强度及初始弹性模量进行分析,得到了该相似材料有关的原始数据和规律。本文初步验证了使用该相似材料模拟深部软岩的可行性,并针对不足之处给出一些合理改进建议,为进一步模型模拟实验提供指导。 |
| 英文摘要: |
| It's difficult to simulate deep soft rock in rock engineering similar model experiment by using traditional similar materials due to its low strength, large deformation and strong rheology. In order to solve this problem, a mixture of 70# asphalt (due to its high output, low cost, visco-elasticity, easy molding and softening) and sea sand was adopted as similar simulation materials for deep soft rock. Uniaxial compression experiment was carried out by continuous loading, and some related parameters for similar simulation material with different ingredient ratios, such as density, compressive strength and initial elastic modulus, were analyzed, and original data and basic characteristics were obtained. The feasibility of using this similar material to simulate deep soft rock is validated and reasonable suggestions are proposed in this paper, which can be used as a reference for further model simulation experiment. |
