| 摘 要： | 通过大量软岩流变试验发现了２种超常力学行为，即软岩蠕变中泊松比出现角值；蠕变和松弛不能用２个线性相关的函数表示。在单参数物性方程的基础上推导出了新的软岩流变物性方程，以描述蠕变和松弛的非线性相关性。实验和分析表明，软岩与一般工程材料相比较有更为复杂的力学特性。

| Abstract: | Unusual mechanical behabiour of soft rocks were found in a number of rheological tests of soft rocks. For example, Poisson ratio is a negative value, and the functions of creep and relaxation are non-linearly dependent. Based on single parameter constitutive law, a new equation for rheologic deformation of soft rocks is proposed to describe nonlinear corelation between creep and relaxation. It is proved by tests that the soft rocks have more complicated mechanical properties as compared with the engineering materials. |
