Experimental Study on Dynamic Compaction Characteristics and Salt Heave of Aeolian Sand
摘要
Abstract
To study the dynamic compaction characteristics and salt heave characteristics of Aeolian sand in the desert area,this paper adopted the Aeolian sand samples from the Gurbantunggut Desert and the Taklimakan Desert as research objects.This paper also conducted structural component analysis,indoor heavy compaction test,indoor MTS vibration test,and salt heave test on the Aeolian sand samples.The results show that:the Cu values of Aeolian sand in both northern and southern Xinjiang are small,with a relatively uniform particle size distribution,poor gradation,a small proportion of fine and clay particles,low cohesive ability,and overall loose structure.The maximum compaction of Aeolian sand in southern and northern Xinjiang is achieved at vibration frequencies of 70 Hz and 68 Hz,and vibration forces of 15+8 kN and 10+5 kN,respectively.When the salt content of Aeolian sand samples in southern and northern Xinjiang increases,the corresponding salt heave volume also increases.In actual engineering,Aeolian sand with low salt content should be prioritized as filler.关键词
