| Abstract: | In order to simulate the folium construction process of roller compacted concrete (RCC) gravity dam, the temperature field and gradual changing thermal stress field developed in Baise RCC Gravity Dam during construction and operation are calculated by means of three_dimensional finite element floating mesh method. Also the effects on distributing rule of thermal stress are analyzed for two kinds of concreting temperatures, ten_day mean air_temperature placement temperature and designed placement temperature, respectively. |

| Keywords: | RCC gravity dam placement temperature temperature field gradual changing thermal field |
