Abstract

Abstract:

Displacement model of single-point monitoring cannot well monitor the safety operation, predict or evaluate the work status of roller compacted concrete dam (RCCD). The expressions of water level, temperature and aging which affect the RCCD displacement were analyzed. In association with displacement observation data, a spatial-temporal monitoring model for the RCCD displacement was established. Engineering example shows that the model has good fitting result, and can be used for real-time monitoring of the running state of RCCD. 

Key words: RCCD, displacement, time and space, monitoring model
