摘要
通过理论分析及现场试验研究得出了风积砂回填料压实度与变形模量、压实度与填料干密度之间的关系,从而为合理确定风积砂回填台背的压实度标准提供了可靠的依据.经实体工程验证所建议的压实度标准合理可行,可为我国西部地区风积砂筑路提供参考.
By means of theoretical analysis and on-the-spot testing,the relationship between compactness and deformation modulus and that between compactness and dry density of the filling are obtained,which provide a reliable basis for settling the compactness standard of aeolian sand filling in the abutment back.Engineering practices have proved that the standard proposed is both reasonable and feasible.It facilitates reference for road construction in west China where aeolian sand is widely used as the construction material.
