摘要
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。
By using finite element method, the whole course numerical simulation of unsteady temperature and creep stress fields is performed in this paper according to the construction and operation conditions of a dam. It is shown that the method presented is more practicable to reveal the change of temperature and stress in a concrete dam compared with the conventional method. Based on the whole course computation of Tong Jiezhi rollcrete dam, the characteristics of distribution and chronic change of temperature and stress in rollcrete dam are studied.
