摘　　要：莱芜水文站是大汶河上游主要控制站,位于山东省济南市莱芜区凤城街道办事处东方红村南,属国家二类水文站。通过利用莱芜水文站实测流量资料和测验断面水工建筑物观测资料进行分析研究,确定不同水位级的堰流流量系数及其变化规律。用水工建筑物推求流量,解决了中、高洪水流量测验技术难题和安全隐患,进一步提高了流量测验的精度和安全性,可满足于水文测验规范要求和整编规定要求。Laiwu hydrological station is the main control station in the upper reaches of the Dawen River. It is located in the south of Dongfanghong, Qingyuan sub-district office, Laiwu district, Jinan, Shandong Province. It belongs to the second class of national hydrological station.Through the analysis and research of the measured flow data of Laiwu hydrological station and the observation data of hydraulic structures at the test section, the weir flow coefficient and its variation law of different water levels are determined. The flow calculation of hydraulic structures solves the technical problems and potential safety hazards of medium and high flood flow measurement, further improves the accuracy and safety of flow measurement, and can meet the requirements of hydrological measurement specifications and integration regulations.
