沙河渡槽工程作为南水北调中线综合规模最大的单体建筑物,应通过充水试验检验渡槽实体质量,为南水北调中线全线顺利通水提供技术保障。文章对沙河渡槽充水试验的必要性进行了论证,提出针对沙河渡槽工程特点的充水试验方案及技术要求,对堵头及堵头作用下的渡槽槽身结构进行复核,证明了试验方案的安全适用。
The Shahe Aqueduct project, as the largest single unit in the mid-route of the South-to-North Water Diversion Project, should verify the physical quality of the aqueduct through water-filling test and provide technical support for the smooth passage of water throughout the mid-route of the South-to-North Water Diversion Project. The necessity of water filling test for Shahe aqueduct is demonstrated in this paper. The water filling test program and technical requirements for Shahe Aqueduct project are proposed. The aqueduct structure of the aqueduct is checked under the action of plug and plug. It is proved that the experimental plan Safe and suitable.
