Combining with the research on losing mechanics of inversely oblique terrane slope, tests of similar materials of limestone are performed. The influences of sand-binder ratio, different binders proportion, and different maintain measures on sample strength are studied. The test results indicate that it is feasible to use sand, plaster and cement to simulate rock body. It is shown that the curves between the strength of plaster sample and the sand-binder ratio are hyperbolic, but that the curves between the strength of mixed sample and the sand-binder ratio are parabola. For both plaster and mixed samples, the bake-dry strengths will decrease with increasing time. The air-dry strength of plaster sample increases with time increasing. But the strength of mixed sample changes irregularly with time increasing. These results provide useful references for rock mechanics simulation experiments.
