岩石脆性破裂 brittle fracture of rocks
The testing result indicates that the seepage character of brittle rock is of district difference before and after failure. So,it is concluded that the seepage pressure makes the effect strongly on the fracture and dilatation of rock.
试验结果反映出脆性岩石破坏前后渗透特性具有明显差异，从而也表明渗透水压力对岩石裂隙张开度与扩展变形起到一定程度的加剧作用。
