摘　　要：开县水位调节坝防渗墙顶与闸坝底部接头要求能适应6 cm的铅直位移和2 cm的水平位移,目前没有可以直接借鉴的变形如此大的工程经验。经研究确定采用柔性接头的结构形式,在对选用的聚氯乙烯胶泥、闭孔泡沫板等柔性材料进行试验研究的基础上,通过1∶1的接头结构模型应力-应变测试分析,提出了适合开县水位调节坝工程的柔性接头止水形式。The joint between cut-off wall and gate dam bottom of the water level regulation dam in Kai County needs to meet the requirements of 6 cm vertical displacement and 2 cm horizontal displacement.A flexible joint form is adopted for the practice.After the experimental study on the flexible materials including PVC daub and closed-cell foam board,a joint model with actual size was established for stress-strain analysis.On the basis of model tests,a suitable flexible joint for the water level regulation dam in Kai County is proposed.
