摘要
水泥稳定碎石基层因其温缩系数和干缩系数较大,极易产生裂缝,这是水泥碎石基层施工急待解决的问题。分析了水泥稳定碎石基层施工中裂缝产生的原因,提出了预防裂缝产生的措施,并给出上基层出现贯通裂缝的处理方法。最后,以广州白云新机场跑道基层施工为例,介绍了采取裂缝防治措施后的效果。
Owing to the fact that both the temperature-contracting coefficient and the dry-shrinking coefficient of the cement-stabilized crushed stone bed are great, cracks are most like to occur in it. Various cracking causes of the cement-stabilized crushed stone bed are dealt with in the paper, with corresponding preventive measures, and treating methods for through cracks suggested. Finally, with the construction of the New Bai Yun Airport at Guangzhou as a practical example, the effects of those preventive measures adopted are described in the paper.
