本文叙述在高围压下用各种靜力学方法及动力学方法测定岩石試件的弹性参量。曾对在地壳中分布甚广的岩石:輝綠岩、玄武岩、花崗岩及石灰岩进行了測定。結果表明,在压力为1—1000公斤/厘米~2范围內,上述岩石的弹性参量均随压力的升高而不断增加。从弹性力学的概念出发,闡明了靜力弹性参量及动力弹性参量的差別,对比了各种不同方法測定的結果,以及它們随压力变化的情况。指出在实践中分別采用靜力弹性参量及动力弹性参量的合理性。

In the following cases a series of mathematical results have also been obtained. 1. The fault seam is located in the centre of the bottom of dam, concrete of dam and rock of foundation possess various elasticity. 2. The fault seam is located in the centre of the bottom of dam, the rock at the left and right sides of fault seam possess vavious elasticity. 3. Fault seam have various locations corresponding to the axis of dam. At the same time photoelastic study is applied to verify the calculated results. The theoritical calculated results agree with the experimental results.

Determination of elastic parameters of rock is the basis for technically advanced and economical underground engineering design. During underground mining the rock mass is always in a state of two or three-dimensional stress, therefore it is more reasonable to determine the elastic parameters of rock in a state of multidimensional stress. On the basis of the stress analysis of the Brazilian test and three-dimensional compression test, a new method for the calculation of elastic parameters is given in this paper....

Determination of elastic parameters of rock is the basis for technically advanced and economical underground engineering design. During underground mining the rock mass is always in a state of two or three-dimensional stress, therefore it is more reasonable to determine the elastic parameters of rock in a state of multidimensional stress. On the basis of the stress analysis of the Brazilian test and three-dimensional compression test, a new method for the calculation of elastic parameters is given in this paper. By application of the results of Brazilian tests of 9 different types of rock, the elastic moduli and Poisson ratios have been calculated and compared with the parameters obtained by uniaxial compression tests. The results indicate that this method is quite satisfactory for practical application.

测定岩石的弹性参数,是作好技术先进,经济合理的地下工程设计的基础。地下工程中,岩石一般处于双向或三向应力状态,因此在多向应力状态下测定岩石弹性参数较为合理。以劈裂试验及三轴压缩试验方法的应力分析为基础,本文提出计算岩石弹性参数的新方法。文中利用九种不同岩石的劈裂试验结果,求出了弹性模量及泊桑比,并与单向压缩试验求得的参数作了对比,其结果证明所提出的方法可以满足实用要求。
