摘　　要：根据在MTS815型电液伺服材料实验系统上完成的混凝土、砂岩、混凝土现浇于砂岩上一体两介质模型和混凝土放置于光滑砂岩上的两体两介质四种模型在单轴压缩载荷下受压应力-应变全过程的试验结果,分析得出了一体模型与两体模型在力学特性与破坏过程中存在较大的差异。前者表现出连续介质的特性,后者表现为非连续介质的特性。This article presents the entire test results of the strain process of concrete, sandstone, bi-material and bi-body specimens obtained from MTS815 rock mechanics test system under compression stress for four kinds of models. A big difference in mechanics characteristic and the destruction process exists for two kinds of models. The former displays the characteristics of a continuous medium ,but the latter exhibits the performance of a non-continuous medium.
