摘　　要：我国是沙漠分布最广泛的国家之一,沙漠地区降水量小、蒸发量大、干燥缺水的气候特点,给沙漠公路路基施工带来了极大不便。本文以新疆塔里木典型沙漠地区风积沙为样品,通过对风积沙颗粒组成、天然含水量分析以及对风积沙样品击实特性的试验研究,提出了沙漠公路路基的干压实技术,以解决沙漠地区筑路用水问题,从而在保证施工质量的前提下缩短工期并降低造价。通过对试验路段的调查和检测,其技术指标均满足设计要求,证实了本文研究成果的可靠性和适用性。实用结果还表明:该技术推广应用于风积沙地区的道路修筑,不仅能稳定路基、增强路面强度,同时对充分利用当地资源、保护生态环境、加快道路建设具有特别重要的经济价值和社会意义。China is a country with widely distributed desert in which climate present is little rainfall, large vol- ume of evaporation, dry and absent of water. It is inconvenience to road construction, due to the large quantity of water using and bad transport condition. According to analyzing the composing and natural water content of wind-blown sand which from the Xinjiang Tarim desert, also experimental research compactness character of wind-blown sand＇ s sample, bring forward the dry compactness technology for solving the problem of water using in the desert area, all of which may reduce the cost and erection time on the premise that the quality of project is ensured. Survey and detection to the trial pavement section demonstrate that the qualifications satisfy the demand of design and proves the reliability and functional of the research. The practical result also illustrates that the technology to the area with wind-blown sand not only make the roadbed stable and strengthen intensity of the road surface, but also make full use of local resource, protecting ecological environment and accelerating road building. That has very important economic value and social meaning.
