摘要
Abstract
The concrete dam in cold area is affected by the diurnal temperature difference significantly,and the short time temperature change process such as cold wave will cause the change of the structure shape of the dam body,and the uneven change of the internal temperature of the dam body is easy to cause harmful cracks.In this paper,the influence of temperature change action on concrete dam is studied,and the stress distribution and crack cracking of dam body are analyzed by establishing the analysis model of temperature field and stress field under the condition of temperature change.The results show that the short-time cooling process has little effect on the interior of the dam body,but it will increase the stress of the overwintering layer on the surface of the dam body,which will make the concrete easy to produce large tensile stress and affect the safety of the dam body.This study can provide reference for dam protection and construction.关键词
