Abstract
This paper presents a thermal-mechanical analysis of a newly cast concrete wall in the construction of a subway station structure, in an attempt to provide a theoretical basis for establishing early age concrete cracking prediction and prevention measures. Thermal and mechanical simulation procedures are formulated by considering time-dependent concrete properties, and numerical analyses conducted for varied constraint conditions. The key model parameters are determined through laboratory tests and inverse solution of in situ measurements. Suggestions are provided for prediction and control of early age concrete cracking in subway constructions.
