摘要
Abstract
The contact surface between layers of dam concrete is a weak part of concrete,which increases the risk of seepage and overall sliding.In this paper,the influence of temperature,humidity and wind speed on the interlaminar properties of the dam concrete is studied,which include tensile splitting strength and chloride ion permeability.The results show that the increase of temperature and wind speed can significantly reduce the interlayer tensile splitting strength and chloride ion permeability resistance of dam concrete.At the same time,the reduction of relative humidity has an adverse effect on the interlaminar performance of concrete.The higher the temperature or wind speed,the more obvious the damage degree of layered concrete.The research results provide reference for dam construction.关键词
