摘要
文中以皖南地区G50 沪渝高速公路怀宁西互通立交工程为例,针对红砂岩作为一种不良路基填料的问题,开展了一系列室内路用性能土工试验,研究了红砂岩作为路基填料的可行性,并结合试验结果,提出红砂岩作为路基填料的设计方案和施工质量控制措施.
Abstract
Taking the Huaining West Interchange Project of G50 Shanghai-Chongqing Expressway in southern Anhui as an example,aiming at the problem of red sandstone as a bad roadbed filler,a series of geotechnical tests on indoor road performance were carried out to study the fea-sibility of red sandstone as roadbed filler.Combined with the test results,the design scheme and construction quality control measures of red sandstone as roadbed filler were put forward.
