【摘要】 物体由液态变为固态时,由于固化压力梯度不为零,所以在它的不同深度上,其力学性质存在着定量的有规律性的差异,并且没有其它能量转化为弹性势能。因此,不管切去它任何较上的部分,其下剩部分都不产生卸荷回弹现象。本文第一作者的这一猜想得到他们所做实验的证明。在地质体中岩石对成岩压力具有"记忆"属性的假说就是建立在这一证据上的。这一实验事实使我们怀疑边坡岩体位移场分析的计算方法中通常所采用本构关系的正确性。更多还原

【Abstract】 The results of the experiment proved the first author’s supposition that when a body changes from the liquid to the solid state there is a quontity difference of regularity in the mechanical properties in their different depths because the solidification pressure gradients are not equal to zero;and there is no elactic potential energy to change from others to in the body and therefore no relaxed-rebound phenomenon to occur in any lower parts of them no matter how cut off the upper parrs.The hypothesis that rock in a geologic body has the properties of memory of rock-forming pressures rests on the experimental evidence.The experimental fact leads us to suspect the correctness of the usual constitutive relations used in computational methods for the analysis of the displacement field in a slope rock mass.更多还原
