As there are less such materials in loess as fossil , plants , slag , etc , which could be used for dating , luminescence dating , especially optically stimulated luminescence dating , was extensively applied to aeolian deposits , for its dating materials were minerals , such as quartz and feldspar 由于黄土中所含的化石、木质、炭屑等适于其它方法测年的物质很少，同时，全新世黄土受年轻有机碳和无机碳的影响较大，致使全新世黄土类沉积物的测年迄今仍缺少理想方法。
On systematic analysis of engineering property of the aeolian sand , we choose cement stabilized aeolian sand , cement stabilized mixture of aeolian sand and soil , lime - fly ash stabilized aeolian sand , lime stabilized mixture of aeolian sand and soil and lime - cement stabilized mixture of aeolian sand and soil as object of research . on the base of the determination and analysis of temperature contraction property , aridity resistance property and strength of the stabilized aeolian sand mixture , this paper mainly analyses influential factors and inherent law of property about the stabilized aeolian sand mixture , and provides scientific foundation for the using of aeolian sand as paving material 本文在系统分析风积沙工程特性的前提下，以水泥稳定风积沙、水泥稳定混合沙土、石灰稳定混合沙土、石灰粉煤灰稳定风积沙和水泥石灰稳定混合沙土作为底基层材料研究对象，在对其温缩、干缩以及强度和模量等性能指标的测试、分析的基础上，研究分析了这些稳定风积沙混合料各性能的影响因素和内在规律，为风积沙用作沙漠地区公路路面材料提供了科学依据。
