风积沙在我国西北部地区分布广泛、储量丰富、取材方便,是西北地区修筑路基的主要材料。而路基压实质量是保证公路整体强度与稳定性的关键。国内现有研究大多是通过重型击实试验或振动试验对风积沙压实影响因素有侧重地进行分析。本文通过经水撼后重型击实试验并结合理论分析与前者的试验成果,研究了各种因素对风积沙标准密度的影响规律。试验方法不同,测得的最大干密度存在差异,为了合理评价路基压实质量,对选取适合的试验方法,提出了评价标准。 Aeolian sand in the northwestern region of China is widely distributed, rich reserves, easy access to material, is the main material for building roadbed in the northwestern region. The subgrade compaction quality is to ensure the overall strength and stability of the road. Most of the existing researches in our country focus on the influencing factors of aeolian sand compaction through heavy compaction test or vibration test. In this paper, the impact of various factors on the standard density of aeolian sand was studied through the heavy compaction test after water shake and the theoretical analysis and the experimental results of the former. Different test methods, the maximum measured dry density differences, in order to properly evaluate the quality of subgrade compaction, the selection of suitable test methods, the evaluation criteria.
