通过对沙颍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；对水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 analysis and calculation of crack control of dam gate in Zhengbukou water control project at the Shaying River, temperature shrinkage stress is the main reason of cracks caused by sluice pier. The research on the development trend of cracks and the safety of sluice pier after cracking , Cracks under normal use load, to meet the strength and stiffness requirements; the sluice gate pier more common cracks proposed preventive measures and remedial measures.
