铁路路基必须具有强度高、刚度大、稳定性和耐久性好、不易变形、纵向变化均匀或变化缓慢的工程性质。然而,在筑路沿线往往缺乏满足高速路堤要求的填料土。因此,对现有填料进行水泥改良是有效的途径之一,并在铁路工程中得到广泛的应用。结合工程实例,介绍水泥改良土技术在某铁路路基工程中的应用,着重介绍了水泥改良土路基的施工工艺及工艺参数的确定,并对水泥改良土施工的质量控制措施、质量检验方法做了说明。
Railway subgrade must have high strength, high stiffness, good stability and durability, not easily deformed, vertical changes or slow changes in engineering properties. However, there is often a lack of filler material along the road to meet the high-speed embankment requirements. Therefore, it is one of the effective ways to improve the existing packing materials and is widely used in railway engineering. Combined with the engineering examples, this paper introduces the application of cement improved soil technology in a railway subgrade project, emphasizes on the construction technology and process parameters of cement improved soil subgrade, and makes the quality control measures and quality inspection methods of cement improved soil construction Description.
