摘要
根据“就地取材”的原则，京沈高速公路国际段有近７０ｋｍ的路基材料采用了当地唯一可取的筑路材料——风积砂。在高速公路建设中如此大量使用风积砂填筑路基，在我省乃至全国尚属首例，为此，建设单位委托国际十四段于１９９７年４～５月份进行了１ｋｍ试验路段施工，本文根据其施工情况，就风积砂的力学性质、技术指标控制、施工工艺等应注意问题等做了简要论述。
About 700km of subgrade materials adopted wind-blow-sand,that is the only one constructional materials in the local,in the international section of Jing-Shen Expressway,accordance with principle of“use local materialsl”. It is the first time that is so much wind-blow-sand was used in the filling subgrade in construction of our Provincial Expressway.For this,the constructional unit built a 100m of testing road in No.14section of international section from April to May 1997.The paper state mechanical property,tehnology control,constructional technology and noticed problem of the wind-blow-sand according to the condition of subgrade construction.
