Abstract EN
Given that spillways adopt a hydraulic thin concrete plate structure, this structure is difficult to protect from cracks.
The mechanism of the cracks in spillways shows that temperature stress is the major reason for cracks.
Therefore, an effective way of preventing cracks is a timely and reasonable temperature-control program.
Studies show that one effective prevention method is surface thermal insulation combined with internal pipe cooling.
The major factors influencing temperature control effects are the time of performing thermal insulation and the ways of internal pipe cooling.
To solve this problem, a spillway is taken as an example and a three-dimensional finite element program and pipe cooling calculation method are adopted to conduct simulation calculation and analysis on the temperature fields and stress fields of concretes subject to different temperature-control programs.
The temperature-control effects are then compared.
Optimization results show that timely and reasonable surface thermal insulation and water-flowing mode can ensure good temperature-control and anticrack effects.
The method has reference value for similar projects.
