红砂岩地带路基施工质量控制的措施

红砂岩地带路基施工质量控制的措施红砂岩地带路基施工质量控制的措施 摘要：由于近几年交通事业的迅猛进展，原有的国道及省道等构成的公路网已不能满足公路运输业的要求，各省区高速公路的大量修建已成为必定。在我国南部省区存在大量红砂岩，由于其材料本身的特别性，以往从未在高等级公路中应用过，只是少量用在低等级公路中作为路基填料，且出现了大量的质量问题。大量红砂岩路堑挖方的去向问题同样摆在湖南是省高速公路建设者面前，假如作为弃方不用，每条高速公路都将产生近千万的弃方，增加几亿元的投资，弃方还将占用大量土地，带来水土保持等问题。如何解决红砂岩施工成为困扰各方面的重要问题。交通部为此专门成立了课题组，讨论红砂岩施工中存在的问题、解决方法及预防措施。本文论述了红砂岩的定义、红砂岩的特征。文中详细指出了红砂岩作为一种路基材料在选用、施工工艺、施工注意事项、稳定性及沉降分析以及红砂岩路基病害的防治对策。 关键词：红砂岩；施工工艺；质量控制 Abstract: Due to the rapid development in recent years of transportation, the National Road and highway, the road network has been unable to meet the requirements of the road transport industry, a large number of highway construction provinces has become an inevitable. In China's southern provinces of the existence of a large number of red sandstone, because of its special material itself, never before in highway application, only a small amount of used as roadbed filler in low grade highway, and appeared a large number of quality problems. Large number of red sandstone excavation to the problem also in Hunan province highway builders face, as if the waste not, every highway will produce discard tens of millions, hundreds of millions of dollars to increase investment, waste will also take up a lot of land, bring the problem of soil and water conservation. How to solve the important problems in all aspects of a red sandstone construction. The Ministry of communications has set up a special ...
