摘要
在RMTS-150型程控伺服混凝土与岩石力学试验系统上对1179个烘干、天然及饱和状态下的沉积岩试件进行了单轴抗压试验,发现试件的弹性模量呈现出一定的规律:随着含水量的升高,岩石的弹性模量呈现下降趋势。通过对泥岩、砂岩、泥质砂岩和灰岩等四类沉积岩在烘干、天然、饱和3种状态下的试件弹性模量的对比,分析水对不同岩性的沉积岩弹性模量的影响程度,提出烘干弹性模量与天然弹性模量、饱和弹性模量与天然弹性模量的关系式并解释水对影响沉积岩弹性模量的机理。
The RMTS-150 program-controlled servo concrete and rock mechanics test system has checked 1179 specimens of dry,natural and saturated sedimentary rocks in uni-axial compressive test.The results have shown the certain rules in the elastic modulus: with the water content increasing,the elastic modulus of the rock shows a downward trend.Trials on the four kinds of sedimentary rocks,including the mudstone,sandstone,argillaceous sandstone and limestone in the dried,natural,saturated conditions have been compared and the results have shown the influence of water on the sedimentary rock elastic modulus of different lithology.The relations between the dried,natural and saturated elastic modulus and the mechanism of the aqueous influence on the sedimentary rock elastic modulus have been illustrated.
