阿其克分水枢纽上下游河道的糙率复核

Roughness rechecking of upstream and downstream river for Aqike water diversion pivot

塔里木河阿其克河口分水枢纽是塔河综合治理的重要工程之一,由于枢纽处缺乏水文资料,在项目的前期阶段对工程规模争议较多。在本工程的水力计算中,关键在于河道糙率的确定,文中根据勘测资料对该段河道的糙率进行了分析复核。

Aqike water diversion pivot is the one of the important comprehensive treatment engineering in the Tarim River.Because of the lack of hydrological data in the pivot,the engineering scale is more controversial during the early stages of the project.In this engineering,the key of hydraulic calculation is lies in the determination of river roughness.The paper analyzes and rechecks the river roughness based on the survey data.
