Abstract

Based on the Nabi hydropower plant, the layout of the safety monitoring device for the roller compacted concrete (RCC) dam is introduced. The variations of some monitoring index during impoundment are analyzed and their evolution rules according to the variation of the water level are presented. The conclusions are made as follows: the osmotic pressure of the dam foundation and the uplift pressure of the upstream curtain are related to the water level; the stability of the dam can be affected by the heat of hydration due to concrete pouring; the water cooling system can effetely inhibit the crack; The impoundment has little effect on the bolt stress meter equipped at the bottom plate of the stilling basin and the reinforcement bar meter located on the surface; there is a negative correlation between their stress state and the temperature.
