| Abstract: | In West China,there is a great abundance of eolian sand in vest expanses of desert. An analysis is made of the optimal water content and maximal dry density of the eolian sand through a series of hammer tests. Through static load tests,its compactness is also studied. Results of these tests furnish a scientific basis for the use of eolian sand in engineering projects. In addition,tests are made for the analysis of the character of interface friction between eolian sand and geogrids,which offers a good help for the design of eolian sand reinforcement. |
