摘　　要：在我国的西北沙漠地区,由于没有较好的路基填筑材料,广泛采用风积沙作为路基填筑材料。在进行路基拓宽施工时,需要将路基的包边土挖除,待风积沙路基填筑完成后,再重新施工路基的包边土。但该方式在新旧路基结合处普遍存在不均匀沉降,导致路面结构损坏。针对上述问题,提出了一种临时拓宽包边土的方式高效风积沙填筑施工技术,不但可以显著提升施工效率,还能够保证施工质量和减少施工对环境的破坏。Aeolian sand is widely used as roadbed filling material in the northwest desert area of China because there is no good roadbed filling material.In the construction of roadbed widening, it is necessary to dig out the edge soil of the roadbed, and then re-construct the side soil of the roadbed after the completion of the filling of the aeolian sand roadbed.However, in this way, it is common to produce uneven settlement at the combination of new and old roadbed, resulting in pavement structure damage.In view of the above problems, this paper puts forward an efficient aeolian sand filling construction technology of temporarily widening the surrounding soil, which can not only significantly improve the construction efficiency, but also ensure the construction quality and reduce the damage to the environment caused by construction activities.
