Abstract
The purpose of this study is to examine the effect of low-heat portland cement and joint for inducing crack which control thermal cracking in thick concrete wall of cut and cover tunnels, through the measurement for massive concrete structures and the numerical analysis by the finite element method. As a result of the examination, it is found out that not only use of low-heat portland cement and joint for inducing crack are effective to control thermal cracking of massive concrete structures, but it is necessary to establish the character of concrete dynamics, specially the compensative coefficient of Young's modulus which is used for the analysis so as to evaluate that effect suitably. Then, the compensative coefficient of Young's modulus corresponding to a kind of the cement is estimated through the measurement and the numerical analysis.
