【摘要】 <正> 五十年代以来,伴随岩石力学的发展,地壳上部应力状态的测量工作逐步得到开展。瑞典的哈斯特于1958年测出了斯堪地那维亚半岛的应力结果,得到了全世界科学家的重视,哈斯特首次证实了地壳中现今应力的存在,并且提出地壳中的应力以压应力为主、在小于200m的地壳中,水平应力大于垂直应力许多倍的观点。七十年代,许多岩石更多还原

【Abstract】 This paper gives a brief introduction about a histy anr present state of earth-stress measurement. It systematically introduces major results of earth-stress measurement home and abroad. It pointed out that a compressive stress is a main stress among the stresses in the earth shell. In the earth-shell with a thickness within 200 Meters, a horizontal stress will be several times greater than a vertical stress. It established a conception of a critical depth. As above the critical depth, a horizontal stress will be great than a lead ball vertical stress. As below the critical depth, a horizontal stress will lower than a lead ball vertical stress. This paper shows some practice to explain that absolute value meastremeut of earth-stress is applied to mines. It also shows the actural profits obtained home and abroad.This paper emphasised on instruments and methods for three practical aud efficient earthstress measurements, and the present state and level of the measuremeut.更多还原
