The claculatedresults show that this numerical analysis method is able to reflect the hydraulic characteristics inthe contract section of slit-type bucket, and also that the bottom pressure distributi0n is in agr-reement with the results of model tests.

• 计算结果表明，本文数值分析方法能够反映窄缝挑坎收缩段的水力特性，底板压力分布与模型试验结果比较吻合。
