摘要/Abstract

摘要： 利用美国HIPERPAV软件对水泥混凝土路面早期裂缝的主要影响因素进行模拟。系统分析研究了路面板厚度、粉煤灰掺加量、养护方式、施工时间、施工季节和切缝等各因素对早期裂缝的影响规律。数据分析结果表明,夏季施工的路面板应力强度比与冬季施工的路面板应力强度比相比要低很多;不切缝的路面板要比切缝的路面板容易产生早期裂缝;另外,选择合理的混凝土配合比、施工时间和养护方式对早期裂缝也有着明显地改善作用。

Abstract: The software HIPERPAV was adopted to analyze the major influential factors of the earlyage cracking of concrete pavement, which including the slab thickness, fly ash, curing method and time, construction time, paving season and time of sawing. The results showed that the stressstrength ratio of slab constructed in summer was lower than that in winter, and the pavement slab without saw cutting was more likely to produce the earlyage random cracking than the slab with cutting. In addition, the proper mixture ratio, construction time and curing method could significantly decrease or prevent the earlystage cracking.

Key words: concrete pavement, earlyage cracking, HIPERPAV
