船闸廊道裂缝预防初探——以京杭运河淮阴三线船闸工程为例

Lock Corridor Crack Prevention Taking Jinghang Cannel Huaiyin 3rd Lock Engineering as an Example

船闸廊道裂缝的产生机理较为复杂,由于廊道独特的结构形式,仅仅从改善施工工艺方面来完全消除廊道裂缝的出现是很难的,从本次京杭运河淮阴三线船闸工程实施过程及结果来看,通过一定的技术措施和改善施工工艺,可使廊道裂缝得到有效的控制,同时避免了有害裂缝的产生。

The mechanism of lock corridor crack is rather complicated due to the unique structure of corridor. As a result construction technique improvement cannot totally eliminate corridor crack occurrence. According to the construction process and results of Jinghang Cannel Huaiyin 3rd Lock, certain technical measures and improvements in construction techniques, can efficiently control the corridor crack and avoid the occurrence of crack as much as possible.
