Simulation Analysis of Concrete Temperature and Stress of Plant Elbow Section of Sluice Dam

Abstract:

In view of concrete structure of dam plant elbows section is complex and strong external constraints, the study of concrete temperature and stress during construction should be carried out by computer simulation. A case of plant elbow section of a sluice dam project is presented where the 3D FEM simulation of instability thermal field and stress field of the concrete structure is adopted after building the 3D finite element model, and the changes and distribution characteristics of temperature and stress during whole process of construction is obtained. The results show that, under the complex constraints condition, the concrete of plant elbow section has greater tensile stress, it can lead to structural cracking, and it is necessary to take appropriate temperature control measures.
