| 摘 要： | 针对节理岩体非均质性特征,利用概化模型、变形等效及当量化处理等方法,研究了梯度应力作用下节理岩体的变形参数变化规律.研究表明:构成岩体的成分不均匀性越显著时,等效弹性模量变化越大,计算得到的最大等效弹性模量当量变化达136%;而当岩体均匀性较好时,等效弹模当量变化小于110%.

| Abstract: | Focusing on the heterogeneous property of jointed rock-mass and combining with generalization model,equivalent deformation theory as well as equivalence methods,the relationship between deformation parameters of jointed rock-mass and stress gradient is put forward.Study shows that the weak part of rock-mass may lessen the comprehensive deformation parameter under high stress gradient,and that the greater heterogeneous component difference in the jointed rock-mass,the greater variation range appears for its ... |
