采用有限单元法,按照大坝的建造和运行过程,进行不稳定温度场与徐变应力场全过程的仿真计算,是揭示混凝土坝温度与应力变化的有效途径,本文通过对铜街子碾压混凝土重力坝的仿真计算,研究了碾压混凝土坝温度与应力的分布及变化规律。
The finite element method is used to simulate the whole process of unstable temperature field and creep stress field in accordance with the construction and operation process of the dam. It is an effective way to reveal the temperature and stress changes of the concrete dam. In this paper, The simulation calculation of concrete gravity dam is carried out to study the distribution and variation of temperature and stress of the roller compacted concrete dam.
