CONCRETE DAM BODY CONSTRUCTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a concrete dam body construction method that has high cracking prevention effect from a perspective of temperature stress control.;SOLUTION: A concrete dam body construction method consists of a first construction period and a second construction period, which do not overlap one another. Average temperature of outdoor air in the second construction period is lower than that in the first construction period. A concrete installation speed in the second construction period is higher than that in the first construction period.;SELECTED DRAWING: Figure 2;COPYRIGHT: (C)2017,JPO&INPIT
