| 摘 要： | 本文应用应变能密度与三向应力圆的等价关系,分析修正了莫尔准则,提出用任意确定静水压力下不同洛德参数的极限莫尔圆包络曲线簇作准则线,即谓之为应变能-莫尔准则线,并引用岩土真三轴试验资料进行验证;最后还得出应变能-莫尔屈服条件,分析了屈服曲面和屈服轨迹的形状等。

| Abstract: | Using the equal value relation between the strain energy density and the 3-dimensinal stress circular, this paper analyzed and revised the Mohr's criterion so as to put forward an adea to use any embraced curve cluster of the extreme limit Mohr's circular of various Lode's parameters (i. e. the strain energy-Mohr's criterion line ) as the criterion line, which has been verified through the real 3-axial tests of rock-ground. Lastly, the writer also obtained the strain energy-Mohr's yielding submission coditions and locus. |
