Abstract
In order to conduct in-depth research on the temperature field and stress field distribution of the concrete cushion layer in Nuozhadu,based on the temperature monitoring data of the cushion layer,combined with the calculation of reservoir water temperature and the temperature of the dam body bedrock,the actual temperature field of the concrete cushion layer was simulated,and the actual temperature field was compared with the inverted theoretical temperature field.At the same time,numerical simulation of the temperature stress of the cushion layer concrete cushion layer during the construction period was carried out.The results indicate that the inverted parameters can effectively reflect the temperature and stress fields during the actual pouring process.After the start of soil and stone filling,there are differences in stress changes in different positions and directions.After all soil and stone filling is completed,the stress in all directions tends to stabilize.关键词
