                                        | 针对CRTSⅠ型轨道板锚穴处混凝土裂纹的不同形式,分析其产生的原因,采取改进锚穴成孔器工艺、降低蒸养恒温温度、覆盖塑料薄膜等措施,取得控制裂纹的实效。 |  
                                        | For the different cracking modes of concrete in the anchors pocket of CRTSⅠtrack slab,this paper analyzes its cause,adopts the measures include improving pore-forming technique in anchors pocket,reducing the constant temperature of steaming,and covering plastic films to obtain actual effects for controlling cracks. |
