电站日调节非恒定流对系缆力的影响研究

Study on the influences of daily regulation unsteady flow in hydroelectric project to mooring force

通过分析实验资料,研究电站日调节下泄非恒定流对系泊船舶系缆力的影响,得到了考虑流速、比降等因素的经验计算公式.该公式是建立在非恒定流的基础上,并且和试验实测成果进行了比较,虽经4个实例运用表明其计算值与模型实测值较吻合,计算精度较高,但由于实例有限,其公式的使用范围需在今后的工作中进一步论证和完善.可以考虑在具有类似条件水电站的非恒定流影响下系泊船舶系缆力计算中参考运用,具有一定的工程适用性和工程实用价值,为日调节下泄非恒定流的进一步研究和航道的整治提供参考.

By analyzing experiment material and influence factors, empirical formulas for calculating the cable dint to the fasten ships under the influences of unsteady flow were established, and it has been verified by correlated data. Good computational accuracy was found by four living examples, the service range of the empirical formula need further argumentation because the instances used are limited There are certain engineering applicability and project practical merit of the empirical formula, lts conclusion provides the reference for the further research of unsteady flow and the channel curing.
