摘要：

利用裂纹孤立原理结合裂纹线场理论，研究剪应力作用下断续多节理线尖端的精确弹性区应力场和脆断区应力场，将精确弹性区应力场和脆断区应力场匹配，确定了脆断区长度和荷载之间的关系，继而从理论上确定了断续任意多节理岩体的强度．该方法可以解决任意多节理岩体的强度特性问题，而且得到的是精确的理论解．

Abstract:

The crack isolating theory was proposed. On the basis of the crack isolating theory and the near crack line analysis method, the elasticplastic stress field near the crack line was analyzed, the laws that the length of the plastic zone along the crack line is varied with external loads were established by the matching condition of the elastic-plastic fields on the boundary, and the strength properties of rock masses were determined. The solution is a function of the geometry of the crack array. The results show that the strength of rock masses depends on the crack spacing, orientation of the cracks, the crack interface friction coefficient and the crack half-length. The conclusions are of important significance for rock masses engineering.

Key words: shear stresses, rock masses with intermittent joints, strength properties, crack isolating theory, near crack line analysis
