沙漠地区高速公路风积沙路基压实方法研究

Study on Compaction Method for Aeol ian.sand Roadbed of Expressway in Desert Area

我国乃至世界在沙漠公路的设计、施工、试验、检测等方面没有较为全面的规程和规范,以指导沙漠路基的施工。本文结合交通部西部交通建设科技项目,在室内试验研究和理论分析的基础上,通过榆靖沙漠高速公路、陕蒙沙漠高速公路(半幅)及靖王高速公路(沙漠段)试验路及大型室内试槽试验研究成果的基础上,提出了沙漠地区风积沙路基施工压实工艺、方法、压路机的参数等。该研究成果已在陕西几条沙漠高速公路上得到应用,解决了沙漠路基诸多技术难题,为国内沙漠地区公路路基施工规范的编写积累了非常重要的资料,同时也取得了显著的社会效益和经济效益。

There are not comprehensive specifications and criterions for the construction of desert roadbed in respect of design?experimention and test in our country even in the world.Combined with the west region communication construction technology project of the Ministry of Communications,we brought forward combination of construction machine?arts and method of compaction?parameters of road roller in reolian-sand roadbed based on examination studying?theory analysis and study of test-road in Jingyu desert expressway?Shanmeng desert expressway?Jingwang express and in-door experimentation of big trough.The result of studying which has been applied in some desert expressways in Shanxi has resolved a lot of difficult problems in desert roadbed construction,it accumulated very important data for desert road bed,and it also acquired remarkable social benefit and economybenefit.
