摘　　要：采用SHPB试验装置对盐岩平台巴西圆盘试样实施了动荷载试验,获得了盐岩在动荷载下的拉伸强度,并与静态实验进行了比较,结果表明盐岩的动态拉伸强度具有明显的应变率相关性。The dynamic tests of a flattened Brazilian disc rock salt specimen are carried out by using the SHPB testing system. The tensile strengths of the rock salt under dynamic loading are obtained, and compared with these under static loading. The test results show that the tensile strengths of the rock salt under dynamic loading has obvious correlations with strain-rate.

关 键 词：盐岩 动态 拉伸强度 应变率
