Study on the Temperature Effects of Super-Large Volume Concrete Construction Based on Finite Element Method
Using the Chongqing East Station underground structure concrete slab project as an example,this study employs numerical heat conduction theory and finite element analysis to construct a finite element model and method for analyzing the temperature effects of super-large volume concrete construction.This provides an objective basis for optimizing the construction control scheme for mass concrete pouring.It is of great significance in reducing temperature-induced cracks in mass concrete,enhancing concrete impermeability,and ensuring the safety and durability of the structure.Based on the constructed finite element model for super-large volume concrete construction temperature effects analysis,the study explores the influence of various factors—such as different types of cement,concrete pouring temperature,concrete water-cement ratio,ambient temperature,and cooling pipe layout—on the central temperature of concrete.This provides a basis for formulating economical,reasonable,and practical temperature crack control schemes.Furthermore,a comparative analysis is conducted with the measured temperature data from the construction process to verify the feasibility of using finite element analysis for optimizing temperature crack control schemes in super-large volume concrete construction.
