摘要
通过对沙颖河郑埠口枢纽工程节制闸闸墩裂缝检测、成因分析及计算，提出温度收缩应力是引起闸墩裂缝的主要原因；对裂缝的发展趋势及开裂后闸墩的安全性研究表明，裂缝在正常使用荷载作用下，可以满足强度、刚度要求；对不闸闸墩较为常见的裂缝问题提出了预防及补救措施。
Based on the inspection, cause analysis and calculation of the cracks in the check gate piers of Zhengbukou Junction Projet on the Shaying River, it is pointed out that stress of temperature and contraction are the main causes of cracks. Through a study on the trend of the cracks and safety of piers with cracks, it is shown that under normal loads, the craks can meet the demands of strength and rigidity. Preventive and remedial measures to common cracks in piers of water gates are put forward.
