Based on viaduct project in Pudong segment of Shanghai middle ring line,floor using technology of cast-in-situ beam supports foundation is introduced,and experiences are summed up.

The construction technology of large acreage entirety wearing terrace;

By analyzing the construction of the large-area concrete ground of a certain metallurgy factory building,this paper introduces some construction technology,technical measures,and experience in settling construction joints and expansion joints etc.

At present there is no standard calculation formula and theory for the reinforced concrete ground of industrial buildings in the aspects of ground thickness,reinforcement grading and base-earth treatment,resulting in the design at will.

The construction of large-area concrete ground floors tends to bring about cracking,which results from the construction,and from the design and others as well,but mainly from the construction.
