Abstract

The design control conditions are uplift displacement or uplift load to spread foundation of bearing uplift load. After testing uplift bearing capacity of aeolian sand of spread foundation on 15 kinds geogrid reinforced conditions, bearing uplift load capacity, uplift displacement, stress, failure surface are studied on geogrid reinforced sand land of spread foundation. It is raised on effective reinforce ways of building geogrids, one and two layer geogrids. According to aforesaid work, uplift displacement mechanism is in research, displacement model and calculation means of uplift displacement control design is advanced.
