洪泛区大粒径填石路基施工工艺及检验技术

Construction Process and Inspection Technology of Large Particle Size Rock Fill Subgrade in Flood Area

在一些发展中国家,为考虑造价成本,在高速公路跨越洪泛区时,放弃桥梁设计方案,而采用填石路基的设计方案。针对大粒径石料颗粒尺寸大、细料含量少的特点,对施工单位在路基施工过程中的填石施工工艺及检验技术进行阐述及分析。

In some developing countries,in order to consider the cost,when the expressway crosses the flood area,the bridge design scheme is abandoned and the design scheme of rock fill subgrade is adopted.According to the characteristics of large particle size and low content of fine materials,the construction process and inspection technology of rock filling in the process of subgrade construction are elaborated and analyzed by the construction unit.
