AbstractFracture problems of rock under compression can be classified by the stress states at the crack tips into two kinds. One is the tension-shear fracture, the other is the compression-shear fracture. The problems of slant crack and wing crack in rock are discussed. The mechanism of two kinds of fracture are analyzed, and the formulae of the stress intensity factors and fracture criteria are obtained. At the same time, the example of crack extension of rock under compression is given to show the validity of the present method and calculation process.
受壓巖體中的裂紋問題 ,可以歸結為壓剪裂紋和拉剪裂紋兩種類型。具體討論了受壓巖體中的斜裂紋問題和翼形裂紋問題 ,對兩種不同裂紋類型的擴展機理進行了分析 ,給出了應力強度因子的計算方法。最后以受單向壓縮的裂紋擴展為例 ,說明了具體的計算模擬過程。
