Temperature crack control analysis for pedestal in jinping-1 high arch dam engineering

Abstract

The feasibilities of temperature control and crack prevention measures in different seasons are researched based on the mass concrete construction simulation of the left bank pedestal in Jinping-1 high arch dam engineering. Pipe cooling is simulated by equivalent method in the computation, the influence of surface heat preservation, parting and some other factors are considered at the same time. The results show the main temperature control project of different seasons is reasonable and feasible. The opening of joints is judged and some suggestions on temperature control and crack prevention are made in the conclusion. © 2008 Science Press Beijing and Springer-Verlag GmbH Berlin Heidelberg Geotechnical Engineering for Disaster Mitigation and Rehabilitation.
