摘要
南阳至邓州(省界)高速公路65%的路段位于中等膨胀土区域,而近距离内却没有适合的非膨胀土填筑材料。经论证,以砂砾作为路基填筑材料,采用土包砂砾的设计方案。文章对砂砾填筑路基的设计方案及施工工艺进行了研究、探讨。
The 65% road section of expressway from Nanyang to Dengzhou lies in the district of middle expansive soft, but there is no suitable reclamation material of non- expansive soil nearby. We adopt the project of soil surrounding shingle using shingle as subgrade reclamation material after investigation. This paper researches and discusses the design project and construction process of filling subgrade with shingle.
