%X Through soil analysis tests and model tests on aeolian sand of typical sand land,the uplift bearing capacity of aeolian sand of spread foundation was tested under 15 kinds of geogrid reinforced conditions. According to the test results,calculation model is defined,and theoretical calculation formula is put forward on uplift bearing capacity of geogrid reinforced sand land of spread foundation. The calculated and measured data are compared and they are closed to each other. The ultimate uplift bearing capacity is researched alone by the tests for sand land and geogrid reinforced materials,respectively. The difference between calculated and measured data is analysed. The effective reinforcement ways of building geogrid,that is,one and two layer geogrids,are proposed. Finally,the problems to be further studied are pointed out.
