摘　　要：诱导缝可以有效地改善坝踵应力分布,防止坝踵拉裂,确保大坝安全。小湾工程于2014年8月进行了泄洪水力学试验,从本次泄洪水力学试验期间的监测数据来看,泄洪水力学试验并未对诱导缝造成太大的影响,诱导缝经受住了泄洪试验的考验,其试验结果可供其他工程参考。The induced joints of arch dam can effectively improve the stress distribution of dam heel and prevent dam heel cracking to ensure dam safety. The flood discharge hydraulic experiment of Xiaowan Arch Dam is carried out on August, 2014. The monitoring data of hydraulic experiment are analyzed and the results show that the experiment does not cause a significant impact on induced joints of dam. The induced joints can safety operated during the flood discharge hydraulic experiment. The experiment results of Xiaowan Arch Dam will provide references for other hydropower projects.
