摘要

为了揭示深部岩体在开挖时所发生的一系列变化情况

需要进行模拟试验研究。简要介绍了深部岩体在开挖洞室或巷道时发生的分区破裂化现象及其发展规律。根据分区破裂化力学现象、模拟试验背景和试验加载条件

运用弹性力学的基本理论

通过分析与计算

确定了采用b/a≥10作为模型几何参数的选取原则。在实验室条件下

可以采用石膏半径b=1 000 mm

钻孔半径a=100 mm的圆柱体模型来模拟深部岩体的分区破裂化现象及其规律。

Abstract

In order to explore a series of phenomena occurring in deep rock mass

a physical modeling test is carried out.The phenomena and laws of zonal fracturing are briefly introduced.According to these and the experimental condition of loading and by using the theory of elasticity

the ratio of the specimen radius b to the hole radius a is taken no less than 10.In the actual physical modeling of zonal fracturing

a cylinder model is selected with the radius of model material

gesso

being 1000 mm

and the radius of hole excavated being 100 mm.
