为了更好地了解岩石在泥浆和水环境中的动力特性，对不同粘土填充的花岗岩厚壁圆柱试样进行了准静态和动态单轴压缩试验。准静态压缩试验结果表明，厚壁圆筒试件中心孔洞和粘土填充的存在对试件的静态力学性能无明显影响。动态压缩试验表明，粘土填充圆柱形花岗岩厚壁试件的动态抗压强度是花岗岩厚壁空心试件的动态抗压强度与中心孔内粘土填充物的动水压力之和，随应变率线性增加。在相同应变速率下，随着粘土含水量的增加和孔径的减小，试样的分散系数增大。
To better understand dynamic characteristic of rock in mud and water environment, quasi-static and dynamic uniaxial compressive tests were performed on cylindrical thick-walled granite specimen with various clay infillings. The results from quasi-static compressive tests show the existences of a central hole and clay infilling in cylindrical thick-walled specimen have no obvious effect on static mechanical behavior of specimens. Dynamic compressive tests indicate that the dynamic compressive strength (DCS) of cylindrical thick-walled granite specimen with clay infilling, which linearly increases with the strain rate, is the sum of DCS of hollow thick-walled granite specimen and the hydrodynamic pressure of clay fillings in the central hole space. The DCS of specimen increases with the increasing moisture content of clay infilling and the decreasing hole diameter at the same strain rate.
