煤和岩石物理力学性质测定方法 第14部分：岩石膨胀率测定方法
Application Summary AI generated
This standard specifies the testing method for determining the swelling ratio of rock, which measures the volume increase of a rock sample when it absorbs water. It is applied in the mining and geotechnical engineering industries, particularly for assessing the stability of surrounding rock in coal mines and underground excavations where water-sensitive clay-bearing rocks are present. The method is used to predict and mitigate risks such as floor heave, tunnel deformation, and support failure in water-rich geological conditions.
