摘要
在有关岩体的三维物理模型结构面教学中,现有的模型存在角度限制、试块难以重复利用等问题,为此,基于工程岩体开挖过程中形成的楔形体岩块类型,该文研制了变角度空间块体滑落模型实验平台,既保证了与岩体物理量的相似性,又能模拟实际工程中碎裂岩体结构面的各种产状,直观地反映不同方位(倾向、倾角)岩块滑落的真实情况。利用该实验平台在岩体力学试验教学中开展相关系列试验,取得了较好的教学效果。
In teaching of three dimensional physical models of structural planes, there are many shortages such as angle restriction and material non recycle use. Based on wedge type of rock blocks due to engineering excavation, a kind of spatial sliding block angle-variation platform is developed. It guarantees the similarity to physical parameters of rock mass, at the same time, it can simulate the occurrence in fractured rock mass, so as to reflect the real situation of block sliding with different dip directions and dip angles. A relevant series of experiments are conducted in rock mass mechanics experimental teaching using the self R＆D experimental platform which represents excellent teaching effectiveness.
