Global and Local Stability Checking Method of Natural Draft Cooling Towers during Construction

Abstract:

Checking the global and local stability of cooling towers during construction is very important to construction safety and reasonable construction process. On the basis of existing researches and by combining the checking method of global and local stability of cooling towers in operation period given in the present design code, this paper presents a method with implementation steps to check the global and local stability of cooling towers during construction. The method is verified to be simple and effective by a cooling tower example. The example analysis indicates that the global stability of cooling towers decreases with the construction height and achieves the minimum when the topmost layer is just built, though it increases bit when all concrete layers reach the design strength. The local stability of cooling towers during construction is poor in the range of 1/5 to 3/5 tower height and should be paid great attention during construction.
