ANALYSIS ON CREEP COMPLIANCE OF CRACKED ROCK
裂隙岩体蠕变柔量分析

Using Betti reciprocal theorem and viscoelastic fracture theory,the formulation of creep compliance of cracked rock under uniaxial stress and hydrostatic stress is deduced. Influence of crack interaction on creep compliance of cracked rock is taken into account by using self-consistent theory,and variation principles of creep compliance of cracked rock with increased crack density parameter and Poissons ratio are analyzed. Difference of creep compliance with and without crack interaction is analyzed,and the creep stability of cracked rock under hydrostatic stress is discussed.
