摘要
通过对科尔沁风积沙的组成、力学性能的研究,提出采用风积沙填筑路基的设计方案,并编制了施工工艺,在通辽至下洼高速公路修筑了试验段。经现场测试,试验段路用性能良好,为今后高等级道路运用风积沙积累了宝贵的经验。
In response to research on composition and mechanics performance of Keerxin wind - blown sand,the paper poses design schemes for filling subgrade with wind - blown sand, and works out construction technology. A trail lot has been constructed on Tongliao - Xiawa Freeway. The field measurement shows that the road usage performance of trail lot is good,which has accumulated valuable experience for high -tytpe highway to apply wind-blown sand hereafter.
