Abstract: This paper presents a new method for settlement monitoring of dam core wall with shape accel array. The shape accel array has the advantages of high precision, high stability, large scale and so on, which has a wide application prospect in the settlement monitoring field for high rockfill dams. In this paper, the basic principle of shape accel array is introduced, and the key technical indexes applied in the high rockfill dam are studied. Then the application of shape accel array at Lianghekou hydropower station is introduced. The results show that the monitoring results are continuous and reliable, and the settlement distribution and change law of the core wall dam along the dam axis are well reflected, which is of great significance for similar projects. Finally, the application of shape accel array in the settlement monitoring of high embankment dam is proposed and the application is recommended for similar projects.

Key words: high embankment dam, shape accel array, settlement monitoring, compatible deformation
