It is common that cracks develop in mass concrete in hydraulic and waterway engineering works.The paper emphasizes on the experiments and study carried out to compare two types of anti cracking concrete with the ordinary concrete during the construction of the lock chamber walls of the second ship lock in Jianbi on Beijing Hangzhou Grand Canal.With the analyses of the causes resulting in cracking in concrete,recommendations are also made to deal with cracking in concrete accordingly,which will be of reference for other ship lock projects.
