新建修武二级公路施工时,A8标段内大量红砂岩路堑挖方,如果弃方不用,需要占用大量土地,带来水土流失等问题;路段处于山垅地区,难有足够的土地来堆放弃方。红砂岩作为一种建筑材料,其路用性质,即具有极强的风化崩解、遇水软化的性能,因此,作为路基材料,需要采取措施预防和处理容易发生的病害。本文为作者在修武公路红砂岩路基施工中一些经验和体会,望能为同行提供参考。 During the construction of Xiuwu Class II highway, a large number of red sandstone grabs in A8 section will need to occupy a large amount of land and cause soil erosion and other problems if they are not abandoned. There is not enough land in the area to pile up abandoned square. As a kind of building material, red sandstone has the characteristics of road use, that is, it has strong weathering-disintegration and water softening performance. Therefore, as a subgrade material, measures need to be taken to prevent and deal with easily occurring diseases. This article is the author of red sandstone roadbed construction in Xiuwu some experience and experience, hope to provide reference for peers.
