某导流洞封堵体温控措施仿真分析

Simulation Analysis of Temperature Control Measures for the Plugging Body of a Diversion Tunnel

以某水电工程导流洞永久封堵体为工程实例,结合工程区气候条件,采用大型通用有限元软件ANSYS,对封堵体混凝土施工期的温度场及温度应力场进行了仿真分析,分析了不同方案温控措施变化对封堵体混凝土温度场及应力场的影响,提出了有效的堵头混凝土施工温控措施,可为类似工程温控措施的优选提供参考。

Taking a permanent plugging body of a diversion tunnel of a hydropower project as an engineering example,combining with the climatic conditions of the project area,using the large-scale universal finite element analysis software ANSYS,the temperature field and temperature stress field of the plugging body concrete during the construction period are simulated and analyzed.The influence of temperature control measures in different schemes on the temperature field and stress field of the plugging concrete is analyzed,and effective temperature control measures for the construction of the plug concrete are proposed,which provides a reference for the optimization of temperature control measures for similar projects.
