The reasons of cracks for floor surface of residential engineering and its preventive treatment

The paper analyzes the formation mechanism of floor-sheets cracks and the caused reasons,and then introduces preventive measures of floor-surface cracks on residential engineering respectively from floor-surface's design,construction,materials and so on.At last,it also proposes some measures to treat and repair the cracks,so as to solve successfully cracks problems of residential engineering for floor-surface and ensure engineering construction operate safely and stably.
