摘要
为改良黄土强度低、易变形破坏的工程特性,在黄土中掺加黄原胶和玄武岩纤维,通过无侧限抗压强度试验探究黄原胶含量和玄武岩纤维加筋率及养护龄期对黄土抗压强度的影响。试验结果表明:与素土相比,分别掺加黄原胶和玄武岩纤维均能提高土体抗压强度和一定程度延性;混合掺加黄原胶和玄武岩纤维时,土体的抗压强度和延性都会提高明显。根据正交试验得到,掺加1.5%黄原胶和0.6%玄武岩纤维时,改良土体的抗压强度最大。
To improve loessengineering characteristics of low strength,easy to be deformed and failure,thus to blend xanthangum and basalt fiber into loess,then through the unconfined compressive strength test probe into impact from added xanthan gum content and basalt fiber archived reinforcement ratio and maintenance period.Tested results have shown that comparing with plain loess,respectively added xanthan gum or basalt fiber can all improve loess mass compressive strength and ductility a certain extent.When added mixed xanthan gum and basalt fiber,loess mass compressive strength and ductility will be all improved obviously.According to orthogonal experiment,when added 1.5%xanthan gum and 0.6%basalt fiber,improved loess mass has maximum compressive strength.
