In order to study durability, crack controlling of concrete structu res and characteristics of concrete at early age in simulated environment, envir onmental simulation test technology is discussed.

The ways of crack controlling in mass concrete were analyzed in those respects of materials, concrete mix design,structure construction,structure details, maintenance methods and the theory about crack controlling in concrete structure.

Research on cracks control for basement wall under finite element analysis;

2m thick mass concrete of the raft foundation with the theory about crack-control in concrete structure caused by drying shrinkage and temperature difference of atmosphere.

By carrying on the technical argument on trial and adopting a series crack-control measure,not detained the after-perfuse sew,construction sew,not established the inflation sew to strengthen,and not added any special waterproof material,the whole 12000m~3 concrete is perfused with success.

This paper discusses the crack-control about the mass concrete of the raft foundation, and analyses the reason of cracks generating in the long concrete wall and in the concrete slab around the core cylinder.
