摘    要:岩石的应力状态发生改变是否能引起岩石的热状态发生改变,是一个值得研究的重要问题,我们在实验室对岩石试件进行实验,实验得出岩石的温度随岩石受到的压力增加而显著增加,在试件破裂前出现明显的破裂温度前兆;实验还发现岩石内部温度随压力变化的不均匀性,不同测温点的温度变化不同,其变化量可相差几度。

关 键 词:岩石  应力状态  地震前兆  温度条件  岩石力学

Abstract:It is worth studying the problem that whether the variation of the thermal state of rocks is caused by the variation of stress state of rocks.The experiments on rocks' samples have been done in the laboratory.The temperature for the rocks increased obviously with the increasing of stress,and there occurred the obvious temperature precursors before rocks' failure.It is also found that the temperature in rocks varied with the inhomogeneous of the change of pressure.The temperature in different points was not the same.The difference of the temperature was several degrees in between.The difference of the temperature varied with the pressure of rocks with the different properties,particle size and structure was very large.
Keywords:Rock stress state  Rock breaking test  P  T condition  Rock mechanical property
