风积沙是沙漠路基的主要填筑材料,其压实特性是影响沙漠公路施工质量的重要因素。天然状态下风积沙为松散状态,承载能力低,工程性能差,为使风积沙路基具有足够的强度和稳定性,需对之进行压实。本文通过室内重型标准击实试验,对风积沙压实特性和压实机理进行研究,并分析影响击实效果的因素。 Aeolian sand is the main filling material for desert subgrade, and its compaction characteristic is an important factor affecting the construction quality of desert highway. In the natural state, the aeolian sand is loose, its bearing capacity is low and the engineering performance is poor. To ensure sufficient strength and stability of aeolian sand embankment, it needs to be compacted. In this paper, through indoor heavy standard compaction test, the compaction characteristics and compaction mechanism of aeolian sand are studied, and the factors affecting the compaction effect are analyzed.
