In order to evaluate the overall pouring quality of rock-filled concrete arch dam,the integrated pouring rock-filled concrete arch dams are analyzed in conjunction with the five arch dams,four among which are used for water storage purposes.The results reveal that the integrated pouring rock-filled concrete arch dams are analyzed in terms of high self-compacting concrete mix ratio,rock-filled concrete construction technology,dam quality inspection and test,and dam operation after completion.All of the test indexes can meet the design criteria,that the dam body pouring quality is generally good,no temperature cracks are observed at any project,and the dam operates normally.Addition-ally,the rock-filled arch dam may be built as a whole,which not only fully utilizes the advantages of the new dam con-struction materials,but also avoids construction interference caused by the dam body joint.Furthermore,it enhances dam pouring speed,which serves as a guide for future comparable projects.
