摘要
2002年对隔河岩枢纽进行了水力学原型观测,内容包括流态、流速、脉动压力等,并取得了成果。1998年枢纽经历大洪水的考验,随后进行抽水检查,发现消力池底板有冲蚀磨损,1999年进行修复处理。2002年泄洪后检查未发现损坏现象。这说明联合消能工效果是显著的,工程质量还是好的,模型试验与原型观测成果基本一致。
In 2002,hydraulics prototype survey was carried out in Geheyan Project, contents included flow pattern,velocity and pulsating pressure etc.. In 1998, the project operated under great flood condition and subsequently dewatered inspection indicated that some erosion and abrasion existed on the bottom board of plunge pool. In 1999,repair treatment was made on damaged section. After 2002 flood, by inspecting again no damage was found. This indicated that unified energy dissipators effect was distinct and constuction quality was good. Model test data are consistent with prototype survey.
