摘    要:在总结以往相似模拟材料特点的基础上,结合深部软岩强度、变形特征,本着相似材料组分简单、模型制作便捷等原则,研制了仅以河砂为骨料,松香酒精溶液为粘结剂的深部软岩新型相似模拟材料。通过对不同配比试样进行单、三轴压缩、巴西劈裂试验,获得了不同配比条件下该相似模拟材料的强度、变形、破坏特征。研究表明,通过简单的配比调配,该相似模拟材料可以较好地模拟深部大多类型的软岩,且具有组分简单、模型制作便捷、力学性能稳定、无毒无污染、价格低廉、一定程度上可重复利用等特点。

关 键 词:深部软岩  物理模拟  相似模拟材料  单轴压缩  三轴压缩

Abstract:On the basis of summarizing characteristics of previous similar simulation materials, combining with the strength and deformation characteristics of deep soft rock, in line with the principle of simple component and modeling convenience of similar materials, a new similar simulation material for deep soft rock was developed, which takes only river sand as aggregate and rosin alcohol solution as a binder. Through uniaxial compression, triaxial compression and brazilian split experiment for specimens with different proportions, the strength, deformation and failure characteristics of the simulated material were obtained under different proportions condition. Results show that through simple proportion modifying, this simulated material can simulate most types of deep soft rock, and has many advantages such as simple component, modeling convenience, stable mechanical properties, non-toxic and pollution-free, low prices, reusable at a certain extent etc.
Keywords:deep soft rock  physical simulation  similar material simulation  uniaxial compression  triaxial compression
