| Based on the existing results abroad and home, combining with the construction of the Shan-Meng desert expressway, the road-related performance of eolian sand with different sediment percentage are studied systemically. The main researches as follows:(1) Through the indoor tests, the paper approaches the physical and chemical properties of eolian sand with different sediment percentage, and the qualitative analysis of the engineering geolgy character are obtained firstly.(2) Based on the compacting test of eolian sand with different sediment percentage, the compacting properties and the compacting mechanism of eolian sand with different sediment percentage are studied.(3) By series of tests for strength and deformation, the strength and deformation properties of eolian sand with different sediment percentage are explored, and the influencing rules of the trength and deformation tests based on the laboratory tests are analyzed.(4) According to the tests above, the variation range of mechanical properties for eolian sand with different sediment percentage are revealed. Following these results, the choice of the biggest dry density is obtained.(5) In view of the results obtained, the road-related performance of eolian sand with different sediment percentage are appraised systemically, and the range of sediment percentage fitting for subgrade material is achieved. |
