石漫滩碾压混凝土重力坝温度效应分析
Analysis of Temperature Effects of Shimantan RCC Gravity Dam
摘要
Abstract
Temperature is one of the main loads of concrete dam, and the adverse temperature load can cause cracks in the dam, especialy during the operation period, the combinat ion of unfavorable hydraulic pressure load and temperature load can expand the cracks, resulting in the damage for the dam safety operation. The Shimantan RCC gravity dam has serious cracks, and regu-lar transverse cracks occur in several sections of the dam. Based on the observed water temperature and air tem perat ure data of the Shimantan reservoir, the large general finite element software ANSYS was used to analyze the temperature field and temper-ature stress field of the dam during the operation period, and to il ustrate the main reasons of the occurrence and developmentof the transverse cracks in aspectof temperature effects, which can provide technical support for reinforcementof the dam.关键词
