某滑坡炭质软岩抗剪强度受含水量影响分析

Analysis of Shear Strength Affected by Water Content of Char Weak Rock in One Certain Landslide

通过对某滑坡其炭质软岩在不同含水量下进行大量的抗剪强度试验,得出抗剪强度与含水量的关系曲线,分析曲线变化特征。因物质成分决定其力学性质,故进一步对岩样进行X-射线分析,得到其矿物成分;同时进行红外吸收谱分析,得到其化学成份。从而从内因上解释曲线变化特征及阐述抗剪强度受含水量的影响。

On the basis of carrying on a large amount of shear streghth tests to char weak rock in one certain landslide under different water content,the relation curves will be drawed which includes shear strength and moisture content,then analyzing the curve's characteristic.Since matter composition determines mechanical property,progressing X-ray analysis of rock specimens further get their mineral composition and meanwhile progressing analyses of infrared spectrum to rock specimens get their chemical composition.Consequently the authors explain the curvilinear characteristic from internal cause that shear strength is affected by water content.
