将信息熵理论应用于黏弹性及黏塑性问题分析，通过单元弹性应变能和单元总应变能所对应的信息熵的对比，发现：不可逆流变应变对应的能量为耗散能，以单元弹性应变能计算的信息熵可以较好地反映结构从无序到有序的演变过程；然后将信息熵应用于不同岩体结构的加速流变破坏分析。结果表明：结构信息熵与节点位移具有良好的一致性；信息熵先因能量耗散而逐渐减小；结构加速流变破坏时，信息熵达到极小值。

Information entropy theory is used to analyze viscoelastic and viscoplastic problems. Based on the comparison of information entropy corresponding to the element's elastic strain energy and total strain energy, it is found that the energy corresponding to irreversible rheological strain is dissipative. The information entropy calculated by element’s elastic strain energy can exactly reflect the development of rock structure from disorder to order. Furthermore, information entropy is applied to the failure analysis of accelerated rheology of different rock structures. It is shown that the information entropy is well consistent with the node ' s displacement. Information entropy reduces gradually as energy dissipates, and then reaches the minimum value when the accelerated rheology of rock structure is destroyed.
