Analysis on the Causes of Crack Formation and New Methods of Temperature Control during Construction of Super-High Arch Dam

Abstract:

In this paper, the mechanism of typical temperature crack is systemically analyzed and the main cause for crack is discussed. Some efficient methods such as surface heat preservation, low temperature placing, interior heat gradient control, cooling height control, selection of water cooling mode have been discussed in depth. In additional, temperature monitoring, feed-back simulation instantaneous and crack risk early-warning are also considered as indispensable component for the temperature control and crack prevention work. At last, a series of temperature control and crack prevention new methods for super-high arch dam are suggested to ensure the safety of the dam under construction.
