摘要
某火电厂水源地勘测进行稳定流抽水试验 ,通过回水达到 3个降程的规范要求 ,并在最后一个降程结束测恢复水位 ,结果水跃值反常、参数失真 ,在此基础上商讨修正及改进的方法。
In pumping test for steady flow in the water source of certain power plant three drawdowns according to the requirements of specifications have been reached through returning water.At the end of the final drawdown the recovery water level is measured.The outcomes are that the value of hydraulic jump is abnormal,the parameters become untrue.Revision and improvement are discussed based on them.
