摘要: 水泥稳定碎石的水稳性和抗冻性比石灰稳定土好,为研究玄武岩玻璃混杂纤维水泥稳定碎石的无侧限抗压强度变化规律和提高稳定性的机理,通过改变水泥稳定碎石中的玄武岩纤维含量、玻璃纤维含量进行无侧限抗压强度试验,得出在25 mm玄武岩纤维掺量为1.0‰、12 mm玻璃纤维掺量为0.8‰时无侧限抗压强度最大值为4.63 MPa,可为今后公路工程提供一些有意义的参考。

关键词: 玄武岩纤维, 玻璃纤维, 无侧限抗压强度

Abstract: Cement stabilized gravel is a semirigid material obtained by adding cement and water to a certain grade of gravel.The stabilized soil has better water stability and frost resistance than that of lime stabilized soils. In recent years, there have been many researches on the nonlateral compressive strength of cement stabilized gravel mixed with single fiber, and there is less researches on the compressive strength of cement stabilized gravel mixed with mixed fibers. Therefore, in order to study the relationship between the unconfined compressive strength of basaltglass mixed fiber cement stabilized gravel and the mechanism of improving the stability. By changing the content of basalt fiber and the content of glass fiber in the cement stabilized gravel, the unconfined compressive strength of the 25 mm basalt gravel size mixed with 1.0‰ fiber and the 12 mm basalt gravel size mixed with 0.8‰ fiber will have a maximum unconfined compressive strength of 4.63 MPa.

Key words: Basalt Fiber, Glass Fiber, Unconfined Compressive Strength
