摘要
以花岗岩、砂岩、片麻岩和页岩等岩样作为研究对象,采用数值模拟方法建立70 mm的立方体岩样模型,在同一压缩载荷函数作用下,采用ANSYS软件对这4种岩样的应力云图和变形图进行研究,并进一步研究相对应的岩样抗压强度。结果表明:在同样的载荷作用下,花岗岩变形最小,对应的抗压强度最大;其次依次为片麻岩、页岩和砂岩。
On the basis on the same compression load, the samples including in granite, sandstone, gneiss and shale were established 70 mm cube specimen model by used of ANSYS. The stress nephogram, deformation pattern and compressive strength of the samples were numerical simulation analyzed. The result is that： when the deformation happened, the stress and deformation of granite is minimal and the compressive strength is maximal, then is gneiss, shale and sandstone.
