STUDY ON METHOD OF TEMPERATURE CONTROL AND CRACK PREVENTION FOR LARGE SLUICE ON ROCK BASE CONSTRUCTED IN WINTER

摘要

Concrete large sluice on rock base is always in stronger constraint and the concrete grade in sluice is usually higher than that in dam. So the temperature control and cracking prevention in such engineering is valuable. A finite element model is created for Liujiadaokou large sluice. Simulation for the construction in winter is put forward by the explicit arithmetic of cooling pipe. According to the temperature filed and creep stress field results, reasonable temperature control measures are presented for reference in construction.
