fis-1615	Zhengbing, Xia; Kefeng, Zhang; Yanfeng, Deng; Fuwen, Ge	A comparative study on dynamic mechanical performance of concrete and rock	2015	6	.pdf	application/pdf	2582	101	43	INTRODUCTION tudies focusing on dynamic mechanical performance of rock materials, a relatively basic branch in rock mechanics, originate from researches on safety protection of atomic energy plant and earthquake engineering [1]. As engineering construction frequently involves rock materials in the last few years, to be specific, national large-scale energy engineering including water and electricity and nuclear power project, transportation including national railway and highway, engineering including blasting excavation and fixed point blasting or facilities establishment including high-level building, bridge, airport pavement and dam all involves dynamic mechanical performance of rock materials under the impact of medium and high strain-load [2], more and more experts and scholars devote themselves to deep study of dynamic mechanical properties of rock materials.	cache/fis-1615.pdf	txt/fis-1615.txt
