摘要
膨胀土是一种特殊的区域性黏土,在我国分布非常广泛,所引起的灾害问题也日益突出。为了提高资源的循环利用,减少膨胀土灾害潜在的影响,笔者进行一系列用废弃轮胎胶粉改良膨胀土的探索。主要是通过室内无侧限抗压强度试验,研究膨胀土及膨胀土-胶粉（expansive soil-rubber,简称ESR）强度特性,进一步分析胶粉含量、含水率等因素对无侧限抗压强度的影响,根据试验结果总结出胶粉改良膨胀土无侧限抗压强度的最佳含量为20%,同时证明了废弃轮胎胶粉改良膨胀土具有良好的效果,从而为膨胀土改良开拓一个新的方法。
Nowadays in China the construction of infrastructure has been expedited.The methodologies to prevent destruction caused by expansive soil have been put in the frontier.Expansive soil is a kind of special regional clay which can be found in many places of China.Geological disasters caused by expansive soil happened in a more and more frequent trend.With the intention to bolster the resources recycling,and meanwhile alleviate the damages to be incurred by the expansive soil,a string of explorations has been undertaken in this paper.In the present study,a uniaxial compressive strength soil test is conducted.It studies the impact of wasted tire rubber powder content and water content for the mixture uniaxial compressive strength.The test results indicate the characteristics of the improved expensive soil shear strength.They confirm the assumption that wasted tire rubber powder can improve the expansive soil greatly.This finding opens up a new improving method to reduce the engineering disaster caused by expensive soil.
