With the open-pit mine slope of Sijiaying Yanshan Iron Mine as an example, biotite granulite specimens from the deep parts of the eastern and northern slopes of the stope were selected for impact tests, freeze-thaw cycle tests and mechanical loading tests, and the fracture characteristics of biotite granulite with different damage degrees under the combined action of freeze-thaw cycles and loading were studied. The results show that under freeze-thaw action, both the mass loss rate and porosity of biotite granulite present approximately linear increase as degree of damage increases. For biotite granulite with different initial damage degrees, the uniaxial compressive strength and elastic modulus all decrease after freeze-thaw cycles. It is shown that intact biotite granulite under loading and freeze-thaw cycles is dominated by splitting failure, while biotite granulite with initial damage is dominated by shear failure and combined tensile shear failure.

以司家营研山铁矿露天开采边坡为例，选取采场东帮、北帮边坡深部的黑云变粒岩进行冲击实验、冻融循环实验和力学加载实验等，研究冻融循环-荷载作用下不同损伤程度黑云变粒岩的破裂特性。结果表明，在冻融作用下，黑云变粒岩质量损失率和孔隙度均随着损伤程度增大而呈现近似线性增大的变化规律；不同损伤程度的黑云变粒岩，冻融后的单轴抗压强度和弹性模量均减小；在荷载和冻融循环作用下，无损伤黑云变粒岩的破坏模式主要为劈裂破坏，有初始损伤黑云变粒岩的破坏模式主要为剪切破坏以及张拉和剪切复合破坏。
