Problems solved by technology

Conventional on-site inversion analysis methods need to simultaneously invert multiple parameters such as adiabatic temperature rise, parameters related to water cooling, and equivalent heat release coefficient based on the surface temperature data of concrete dam blocks, in order to obtain the correct surface heat release coefficient. The inversion of multiple parameters often converges to the local optimal solution rather than the global optimal so...

Abstract

The invention provides a real-time inversion analysis method of concrete dam block surface heat emission coefficient. The real-time inversion analysis method monitors climatic conditions around a damblock, dam block surface temperature and a temperature inside the dam block in real time; temperature variation parameters inside the dam body are calculated by a direct solution method, by combiningwith shape parameters and material thermodynamic and mechanical parameters of the dam body, an interpolation and iteration method is used for inversely analyzing and determining the dam block surfaceheat emission coefficient based on a finite element method, temperature control and cracking prevention can be carried out better, and the accuracy and calculation efficiency are higher.

Description

technical field [0001] The invention relates to a real-time inversion analysis method for the surface heat release coefficient of concrete dam blocks, belonging to the technical field of water conservancy and hydropower engineering. Background technique [0002] Temperature cracks are common cracks in concrete dam blocks. Common temperature control and anti-crack measures include: lowering the pouring temperature, passing water for cooling, and surface insulation. Surface insulation measures are the most effective measures to prevent cracks on the surface of dam blocks during construction. In order to better control the temperature of the concrete dam block and prevent cracking, it is necessary to know the heat release coefficient of the surface of the dam block and control the trend of the surface temperature change of the dam block in real time. [0003] The surface heat release coefficient of concrete dam blocks can be obtained through experiments or in-situ inversion ana...
