摘要
文中对粗砂岩和细砂岩两种岩石单轴受压蠕变试验中，横向变形独立发展现象进行了定性描述与定量分析，并以岩样内部裂隙发生发展为出发点，对该现象机理进行了分折，认为在一定水平的应力下，岩样内部裂隙随时间不断发展，是横向变形独立发展的原因。
In this paper, the independently development of lateral strain under uniaxial compression creep tests to grit sandstone and fine-grained sandstone ate qualitatively descripted and quantitatively analysed; meanwhile, basde on crack initiation and propagation in specimen rocks, the mechanism of this phenomenon are analysed; and the aothor bellyes that under the given stress the uninterrupted propagation of cracks in specimen rocks are the reason of independently development of lateral strain.
