摘要
本文通过对大型商业有限元软件ABAQUS的二次开发,对混凝土坝在施工期与运行期复杂温度、变形及应力场进行模拟仿真.本文开发的软件可考虑实际工程中各种荷载、边界条件与施工过程及工程措施.本文还利用该软件对某弧形重力坝8#～9#溢流坝段长达3年的施工与运行过程进行了完整的数值计算,计算结果表明该模型能很好地模拟混凝土坝施工期和运行期的温度和应力场.
On the platform of ABAQUS, a simulation procedure of thermal stress fields of concrete dams during construction and operation periods is presented in this paper. The procedure can simulate many kinds of loads, boundary conditions and engineering measurements. Two monoliths of an are gravity dam are simulated in its construction and operation periods of 3 years. The results show that the presented procedure is very good to simulate the thermal stress fields of concrete dams in the construction and operation periods.
