摘要/Abstract

摘要： 依托贵州省黔中水利枢纽工程，采用无人机、高速摄影和表面流场测量系统LSPIV等设备，对溢洪洞泄洪时进出水口的流速分布及挑流水舌形态进行了测量分析，得到了溢洪洞进出水口表面流场的流速分布、挑流水舌形态和泄流量等一般水力特性，为实际工程运行中水力学特性数据的获取提供了一种新的思路和方法。

Abstract:

To monitor the velocity distribution and pattern of the water jets at the spillway inlet/outlet, equipment such as drone, high-speed photography, large-scale particle image velocimetry (LSPIV) and et al. are adopted for the Qianzhong water conservancy project. As a result, the general hydraulic characteristics are obtained. It can be further used in the acquisition of hydraulic characteristic data in project operation.
