摘　　要：基于广东省清(远)连(州)一级公路升级改造(高速)项目中滑模贫混凝土基层试验路铺筑时产生的开裂问题,详细分析了产生的原因,结合施工规范、有关文献及试验路施工情况,提出了滑模贫混凝土基层施工时应采取的控制开裂措施,可供高等级公路滑模贫混凝土基层施工时参考。According to the problems of cracking produced in the process of paving the experimental road with slipform base lean concrete for the project of rebuilding and upgrading Qing-Lian （Qingyuan-Lianzhou, Guangdong Province） First Class Highway, the possible factors resulting in these problems are analyzed in detail. On the basis of the construction standards, some related literatures and the construction of the experimental road, several measures are put forward to control cracking in the construction of the slipform lean concrete base. And these measures may serve as references to the construction of the concrete road base of the high grade highway with slipform.
