摘要
采用两种不同的养生方法、不同饱水条件、压实度分别对不同养生龄期水泥稳定土的无侧限抗压强度进行测试,研究以上因素对水泥稳定土无侧限抗压强度的影响规律。结果表明:养生方法二对水泥稳定土的早期强度的提高更加显著,且能够提高试件的无侧限抗压强度的稳定性;饱水条件降低能够降低水泥稳定土的无侧限抗压强度;通过提高压实度能够显著提高水泥稳定土的无侧限抗压强度;养生龄期对水泥稳定土无侧限抗压强度具有显著影响,随着时间的增大,其强度持续增大。
By use of two curing methods with different saturated conditions and degree of compaction,the unconfined compressive strength of cement stabilized soil in different curing age was tested respectively to study the law how the above factors influence the unconfined compressive strength of cement stabilized soil.The results show that the curing method II may enhance the early strength of cement stabilized soil to a more significant extent,simultaneously,improve the stability of unconfined compressive strength of the specimen;the saturated conditions may reduce the unconfined compressive strength of cement stabilized soil;with the increase of compaction degree,the unconfined compressive strength of cement stabilized soil may be enhanced greatly;the curing age has an obvious effect on the unconfined compressive strength,and as time goes by,this strength increases continuously.
