摘要: 基于弹性力学的基本理论,综合考虑温缩应力和干缩应力对裂缝的影响后,提出了水泥稳定碎石基层预锯缝 间距的计算公式,分析了基层厚度、温差和锯缝间距的关系。并且以重庆地区为例,给出了不同基层厚度锯缝间距 的建议值。

关键词: 半刚性基层, 锯缝间距, 反射裂缝

Abstract: Basing on the basic theory of elasticity, the computation formula of the pre-cracking spacing of cement-stabilized crushed-stone base is proposed, with the consideration of stress-reduction and shrinkage stress on the impact of cracks. And then the relationship among basic thickness, temperature difference and the spacing of pre-cracking is analyzed. Taking Chongqing region as an example, the recommendation values of the spacing of pre-craeking at different basic thickness are given.

Key words: semi-rigid base , the spacing of pre-cracking , reflection crack ;
