摘　　要：从原闸抗滑稳定不满足要求问题着手,重点分析原闸的基础加固方法。通过实际的受力工况及受力过程计算分析,提出了较合理的加固措施:在原闸底板的上游侧拼宽一块新底板,增补灌注桩,使新老底板联结为一整体,共同承担荷载,解决了闸室抗滑稳定的问题。对灌注桩施工方法、工艺、检测及拼宽底板的结构措施等进行了总结,为今后其它类似工程提供参考。Due to the anti-sliding stability of the original gate can not meet the requirement,the foundation reinforcement method is specifically stressed for reinforcing the original gate.The reasonable reinforcing measures are put forward after calculation and analysis of the actual bearing status and the bearing process.A new base plate is widened on the upstream side of the original gate base plate,with the cast-in-place piles added,so as to get an integrated effect of both the original and the newly placed base plates for sharing loads,thus the gate chamber stability problem against sliding has been solved.All the structural measures such as the construction technology of the cast-in-place piles and inspection and widening of the base plate,etc are summarized,providing references for other similar project in future.
