为了提高水泥土的受力性能,利用玄武岩纤维的加筋增强效果,探讨在水泥土中掺入玄武岩纤维以改善其力学性能的方法.采用不固结不排水三轴试验,对玄武岩纤维水泥土的抗剪强度进行研究,了解其强度及变形特性.结果表明:玄武岩纤维的掺入使水泥土的黏聚力有较大幅度的提高,且二者大致呈正比关系;应力应变曲线大致可以分为3个阶段:线弹性阶段、塑性屈服阶段、峰值软化阶段;玄武岩纤维的掺入具有类围压作用,对水泥土强度具有明显的提高作用,且增大了其塑性变形.
In order to improve the mechanical properties of cemented soil, basalt fiber reinforced reinforcement effect was used to explore the incorporation of basalt fiber in cement soil to improve the mechanical properties of the method.Using the uncured undrained triaxial test, basalt fiber cement soil The results show that the incorporation of basalt fiber increases the cohesion of cement and soil greatly, and the two are roughly in direct proportion to each other. The stress-strain curve can be roughly divided There are three stages: linear elastic stage, plastic yield stage and peak softening stage. The incorporation of basalt fiber has the effect of confining pressure, which can obviously improve the strength of cement soil and increase its plastic deformation.
