摘要
路基边坡作为道路工程项目建设核心内容,对道路工程路基、边坡施工合理设计和规划是非常重要的。以红光路市政工程为研究背景,结合工程重难点,重点分析半填半挖及不良地质路基及其高边坡防护施工,采用双向拉伸土工格栅及土层换填的方法,并从测量放线、路基碾压、骨架护坡、喷播植草等方面分析各施工要点。结果表明:采用双向拉伸土工格栅及土层换填的方法对半填半挖及不良地质市政路基及高边坡防护施工的处理,不仅能确保土层承载力,同时可以保证工程质量及施工安全。
As the core content of road engineering project construction,subgrade slope is very important for the reasonable design and planning of subgrade and side slope.Taking the Hongguang Road Municipal Engineering as the research background,combined with the key and difficult points of the project,the protection construction of the half filled and half excavated,subgrade with unfavorable geological conditions and high slope was analyzed.The method of biaxial tensile geogrid and soil layer replacement was adopted,and the construction points from the aspects of Surveying and setting out,subgrade rolling,skeleton slope protection and grass planting by spraying were analyzed.The results show that the two-way tensile geogrid and soil replacement method can not only ensure the bearing capacity of soil layer,but also ensure the engineering quality and construction safety.
